I'd say about 5-10 days depending on where you live & how fast the mail/shipping is in your area. I've not had 1 issue with Temu

I live in WI and I receive my orders within a week. It's not like ordering from the Wish app where items come from China. Everything that I have received & returned has had a US address in CA

Temu:
Status code 429. It's telling me I don't have an Internet connection...Can you give me your support mail, bc I cant write you on support chat? :(

Hello Karen, we work with UPS and USPS to ensure that your order is delivered timely and efficiently. Most packages arrive between 7-15 business days. You can track your shipping status and see your expected delivery date directly in the Temu app or on Temu.com. If the tracking status is not updated for 15 days, you can request a full refund and keep your items when they arrive. If your order arrives later than the estimated delivery date, you will receive a $5 credit (for standard shipping) or $13 credit (for express shipping) as a sign of appreciation for your patience. Finally, if your items do not arrive, arrive damaged, or do not match the description or photos, you will be offered a full refund under Temu's Purchase Protection program (https://www.temu.com/temu-purchase-protection.html). Customer satisfaction is the most important to us and we are constantly working to improve our service quality. If you don't mind sending us your order ID, please email me at candy.wong@temu.com, message us through Temu.com or Temu app live chat, or call us (1-888-495-8368) so we can help you locate your packages and resolve this issue as soon as possible. Best wishes, Candy

The items come from China, so it takes a while to arrive plus clearing customs, and local travel.
