Shoppers Post Office Hours: Saturday, Sunday & Myrtle Beach

If you’ve ever shown up at a post office on a Saturday only to find it closing in an hour, you already know: weekend postal logistics are a maze. USPS retail windows have shrinking Saturday hours at most locations, and Sunday isn’t an option for standard mail at all. Here’s what actually applies if you’re mailing from the Myrtle Beach area — and how to work around the gaps.

Typical Last Collection: 11:15 AM – 4:15 PM (Sat) · Saturday Retail Window: 9 AM – 12 PM · Sunday Delivery: Priority Mail Express only · Locator Tool: tools.usps.com

Is Saturday a working day for the Post Office?

Yes — and it’s a fully operational day for mail delivery. USPS treats Saturday as a regular business day for First-Class Mail, Priority Mail, and USPS Ground Advantage, all at no extra cost. Easyship notes that these services flow through the system the same way they do Monday through Friday.

The catch is retail access. Post office lobbies and counters open on Saturday, but the window is tight. In the Myrtle Beach area, most locations run 9 AM to noon, with CPU Cherry Grove Beach offering a slightly wider 9 AM to 1 PM slot. USPS Tools confirms this pattern holds for the North Myrtle Beach, Myrtle Beach, and Carolina Forest locations.

Peak avoidance times

Saturday mornings get busy. If you’re mailing packages, aim for early — before 10 AM — to avoid the queue. Accio delivery guide recommends Priority Mail or Priority Mail Express if you need a guaranteed Saturday delivery window; First-Class depends on your location’s standard cutoffs.

Can you use a Post Office on a Sunday?

Standard retail: no. Every USPS location in the Myrtle Beach area is closed on Sunday for counter service. USPS Tools lists all verified locations as Sunday-closed, and Shopify e-commerce policy confirms this is the national policy — closed Sundays except for Priority Mail Express and Amazon packages.

Delivery is a different story. Priority Mail Express guarantees Sunday delivery by 10:30 AM in most areas, with later windows in rural zones, according to Easyship. Amazon packages also show up on Sundays in covered ZIP codes, per Accio, with a 9 AM – 6 PM delivery window.

Alternative options on Sunday

If Sunday is your only window, your choices narrow to premium services or third-party carriers. FedEx and UPS operate on Sundays in many markets and may be worth checking if USPS doesn’t serve your ZIP code. Self-service kiosks exist at some locations nationwide — Post Pony kiosk guide notes one in Wilsonville, OR — but Myrtle Beach availability isn’t confirmed in current data.

What time do post offices pick up mail?

Last collection times on Saturday vary by location, and the spread is wider than most people expect. At CPU Cherry Grove Beach, the final pickup is at 11:15 AM. At the North Myrtle Beach USPS on 6th Avenue South, it’s 4:15 PM. That’s a five-hour gap between two locations in the same market.

For weekday deliveries, USPS Official states that service standards do not count Sundays or holidays when calculating delivery windows — meaning if you drop mail on Saturday or before a holiday, the clock starts the next business day.

Daily pickup patterns

Standard mail pickup follows a consistent weekday pattern, but Saturday last collections are location-specific. Closo notes that Saturday delivery runs 9 AM to 5 PM nationally, with most packages arriving by 2 PM. During Q4 peak seasons, Saturday deliveries can extend to 9 PM in some areas.

What are the best hours to go to the post office?

For retail transactions — buying stamps, sending packages, using counter services — Saturday before noon is your only real weekend option. Sunday has no retail access. The best general strategy: Saturday morning, ideally before 10 AM, to avoid the lunch-hour crowd and still catch the full retail window.

If you’re a sender rather than a counter customer, Saturday delivery runs all day. Easyship confirms that First-Class Mail, Priority Mail, and USPS Ground Advantage all flow on Saturday as standard services.

Using the USPS locator tool

The most reliable way to confirm hours is the official USPS locator at tools.usps.com. Enter your ZIP code or address, and you’ll see exact retail hours, last collection times, and Sunday availability for your specific location. This is especially useful for finding the handful of locations that deviate from the standard 9 AM – 12 PM Saturday model.

Can you send mail from Shoppers Drug Mart?

The Shoppers Drug Mart question applies primarily to Canadian locations — those stores host post office counters in partnership with Canada Post. Hours at those counters can differ from store hours, and not all Shoppers locations have a post office inside. The same principle applies in the US context: if a retail location hosts a postal counter, its hours may not match the host store’s hours.

For Myrtle Beach specifically, the USPS retail locations are standalone post offices, not counters inside other retailers. But the locator-driven principle still applies: always verify the postal counter hours separately from the host location’s hours, especially on weekends when windows are narrower.

Post office services inside stores

Where retail counters host postal services, hours variation is the biggest practical issue. Shopify notes that post offices nationwide have limited Saturday hours and are closed on Sundays — and this applies to any counter, whether inside a grocery store or a standalone facility.

Hours variation note

Without a specific location, exact weekend hours for hosted postal counters can’t be confirmed from current data. The general rule: hosted counters follow the same Saturday limitation (typically under 3 hours) and Sunday closure as standalone locations. Use the official USPS locator to confirm before visiting.

Saturday is considered a regular business day for USPS, so most services offer Saturday delivery at no additional cost.

For Myrtle Beach-area shoppers, the postal schedule comes down to one hard rule: Saturday morning is when things actually work. Retail windows close at noon almost everywhere, last collection times are scattered across a five-hour window depending on which facility you use, and Sunday is a dead end for counter service. Priority Mail Express is the only Sunday option if you’ve left it too late — and it carries a premium price tag. The move is simple: verify your specific location’s hours on tools.usps.com before you go, and plan Saturday morning for anything that needs a physical counter.
