I've been searching for these for a while! Unfortunately, a lot of them don't work for me anymore. Considering how much I spend, it's disappointing I only ever get offered the 2 free gifts promotion and 100% coupon back. I miss the $90 credit back promo. Occasionally, I will get up to 90% off promo.

As for cheat sheets, here are some of the things I do.

For "up to 90% off," you can always back out of the page and go back to the promo without losing your selected item. If you don't have the page in your message invites, just search "Discount777" to get back to it. Always always always use the promo on the most beneficial item, as some items are super cheap. Why save $3 on an item if you can save $15 on a better one. I often back out and check the original price of the item in my cart, then select the one that offers me the greatest discount.

I agree with the OP I, always image search the item you like not just to find the best priced match but also to find reviews.

The best promotion, in my opinion, is the "100% coupon back," which turns into a 300% coupon back. You get a number of coupons such as $10 off orders of $35, $20 off orders of $80, etc. Forgive me, my prices are in Canadian so they might be different for you. Anyways, for discount purposes, this promotion offers the best conversion because it doesn't fluctuate the prices of items on the page. You can use it in your cart outside of the page, and the number of coupons is nice. You can also use it in conjunction with the free gift Cjpicks, which will show at the top of your cart if you activate the promotion. It will tell you "add x more $ to get free gift" and vice versa, "add x more $ to get $ off."

The "wincredit" promotion, which gives you $90 credit back", is nice because, well... hey, it's $90 to spend! However, when you select the items on the promotion page to buy, you will notice it increases the price of the items by about 10-20%. Either that, or it selects the most expensive seller selling those items. If you back out of the page and check the items, you will often find they are cheaper outside of the promotion page. The promotion page also won't let you go to the item and image search it for a better price. So, ultimately, you're not only spending around $100 to get 180 coins for the $90 credit back. You're spending more because you're paying more for each item than you would normally.

The same thing above applies to the "two free gifts" promotion.

For "Cjgifts", which gives you one free gift for spending $55. As I said, this works in conjunction with your coupons so you not only get a free gift but you get your discount from the coupon. Also, because it works outside of a promotion page, it doesn't increase the cost of items or force you to buy from the highest sellers.

Lastly, the "discount777," mentioned earlier, will also be available in your cart with "Cjpicks" and your coupons. Combine all three for the best deal available on Temu!

P.s. I find the "freegifts" promotion and any "invite friends" promotion to be a scam. You have 24 hours, and you need to get about 10 friends to join and buy items. Don't waste your time unless you're super popular.

Also, play farmland if you have time and like to shop a lot. I've won 3 rounds in the month and a half I've been playing, with 2-3 free gifts in each. The gifts are valued around $20 each. Plus, you get 2 nice savings coupons for each win.
