AliExpress is having a 6th Anniversary Sale and a huge number of merchants are participating - log in, add items to your cart, and observe your total. Now, long into the app and compare the difference - on my computer my total came to $128, and on the app it was $87. Spend over $52 and you get a $6 coupon that automatically discounts your cart (APP ONLY).
Here are 2 great deals I picked up:
10-piece makeup brush set (generic version of the famous Artis brushes all the YouTube gurus are using) - $65 online, $26 on the app

Costume jewellery from the merchant 'Zhouyang' - I own some of these rings and they look like real diamonds - $5 online, $1.80 on the app

Aliexpress is famous for its knock-off versions of authentic products. While I would never recommend purchasing these, I hear the fake pokemon cards, Nike runners, Kat Von D eyeshadow palettes, and Tarte brushes are virtually indistinguishable from the real thing. ;)
There's something for everyone. Easiest way to navigate this sale is to find what you want using your computer (tick the Anniversary Sale box, sort by 'orders'), find it cheapest, get your cart ready, and then check out using your phone.
I think their sale started 2 days ago. I had a look at some stuff I wanted. On desktop you can see what the app pricing would be. I think if you hover over the item, the app pricing will show up. It seems to me the "sale" pricing is quite similar to Banggood normal pricing, so that's why I didn't post anything on here.
Also, I have had a few problems with Aliexpress orders where the goods are knockoffs. The sellers always request I change the claim to damaged goods rather than counterfeit before they would issue a refund. I guess this allows them to continue to operate without drawing too much attention from Alibaba themselves.
