There are a lot of nootropic stores that offer modafinils and armodafinils at low prices, and Afinil Express is no exception. Afinil Express sells pills in packs of 20, 50, 100, 200 or 300 and they get cheaper per pill the more you buy. Pills get as low as $0.80 a piece for Modvigil – not a bad deal if you’re looking to buy in bulk.
