Both options can work, but shopping on Walmart.com typically gives you more choice. You’ll find shipping tubes in a range of lengths (for example, 12 to 48 in), diameters, and shapes (round or triangular), plus multipacks with end caps for bulk needs. That variety can help you match the tube to your poster, blueprint, or document.

• Buying here: Compare sizes and wall thickness, check product details, and choose pickup or delivery where available.
• Buying at a carrier counter: Convenient for a single shipment, though selection may be limited and availability can vary by location.

Whichever route you choose, measure your item first and confirm your carrier’s size guidelines.

Both shapes are commonly used, and many carriers accept them when packed correctly. Policies can differ, so it’s wise to review current guidelines before you ship.

• Secure end caps: Tape both ends so they don’t loosen during transit.
• Measure carefully: Length and diameter affect acceptance and how rates are calculated.
• Label placement: Triangular or square tubes offer a flat panel for labels. For round tubes, use a clear label pouch or extra tape to help the label stay put.
• Avoid overfilling: Leave space for caps and protective padding.

Checking your specific service’s size and packaging rules can help avoid delays or additional handling.

You can find a wide selection of mailing tubes on Walmart.com.

• Search terms: Try “mailing tubes,” “poster tubes,” or “shipping tubes.”
• Use filters: Narrow by length, diameter, shape (round or triangular), color, and pack size.
• Check details: Look for interior dimensions and whether end caps are included.
• Fulfillment options: Choose delivery or store pickup where available, based on your location.

If you ship often, consider multipacks to keep your mailing station stocked. For in-store assistance, ask in the Office Supplies area.

There isn’t one set price. Shipping costs can vary based on several factors.

• Size: Length and diameter influence how carriers rate the package.
• Weight: Heavier contents generally cost more to ship.
• Destination and speed: Longer distances and faster services typically increase cost.
• Packaging: Some services may handle large or unusual shapes differently; policies can change.

To estimate, pack the tube, then weigh and measure it. Use your carrier’s online rate tool or ask at a local shipping counter. Choosing the smallest tube that safely fits your item and packing efficiently can help manage costs, but results may vary by service and destination.

Pick a tube that fits your poster without forcing a tight roll or leaving too much empty space.

• Length: Select a tube slightly longer than the poster to accommodate end caps (about 2–4 in extra works for many prints).
• Diameter: Around 2 in suits a single, thin poster; choose a wider diameter for thicker paper, laminated pieces, or multiple items.
• Wall strength: Heavier-duty cardboard can add rigidity for longer trips or delicate work.
• Shape: Triangular or square tubes don’t roll and offer a flat surface for labels; round tubes are compact and common.
• Protection: Wrap with tissue or kraft paper and tape both caps securely.

Measure first so you can match length and diameter before you buy.
