Aerie Semi-Annual Sale (Undies 5/$16.50, Bras starting at $15)

Disclosure: This post contains affiliate links.
I've said it before, but Aerie undies are THE FUCKING BEST. The most comfortable, the cutest, the best range of styles, the most durable. The ones on sale for 5/$16.50 are a limited selection, but there are some good comfy cotton ones that don't look dumpy. No code needed.

Pro tip: If you buy cute black underwear, all of your underwear is period underwear.

If you have a Shoprunner account (invite link), you'll get free two day shipping too (also worth it if you regularly shop at drugstore.com or Petco).

Aerie underwear is the best underwear (7 pairs for $26.50) (UPDATED)

ETA: I'm finding that the 20% code won't combine with the 7 pair promotion. Sorry, the original announcement of the sale I saw said it included marked-down items, but the underwear must be an exception. All the stuff about the underwear being the best still stands, though . . .

Here's a link to all the 7 for $26.50 underwear. I have the solid and lace boybriefs and the boy shorts, and they are all really cute and good quality. They've been going strong for almost a year now. Plus they are the most comfortable underwear I have ever owned, and I am really picky (especially about things riding up my ass - these don't).

Use code 22039351 for 20% off everything else from AE and Aerie until June 2. 

If you have a Shoprunner account (invite link), you can also get free 2-day shipping (works at drugstore.com, beauty.com, and Petsmart, too).
