Shipping Policy & Manufacturing Info
Shipping Policy & Manufacturing Info
Our shirts are made when ordered.
Most orders ship out within a few days of being placed from our warehouse in California. Orders are generally delivered 3-8 days after being shipped. Except noted below, all packages are sent USPS 1st Class.
Our current manufacturing & shipping options are:
• Standard Shipping ($5.99+)
• Shipping and Expedited Manufacturing ($10.95+)
If you are in a rush, there are 2 options that may help:
1.) Choose "Shipping and Expedited Manufacturing" in checkout. Orders using this option jump to the front of the line when orders are next processed and will be printed before the rest. Especially useful during busy/holiday shopping times.
2.) Order more items. Packages over 1lb will automatically be sent via USPS Priority Mail due to the weight, so will often save a day or two of shipping time. This is generally 4-5 smaller sized items, or 3-4 of a bigger size.
Please Note:
• We do not guarantee shipping or arrival dates.
• All manufacturing and shipping times are just estimates and will vary.
• Orders shipped outside the US will take longer depending on where being shipped.
