I only go to Sally's when they have this sale, and I only go for the nail polishes, though I like to browse around and see what they have too.
I was able to squeeze some time in yesterday to stop by the store, and I picked up two awesome nail polishes!
I purchased Orly's "Boho Bonnet" and China Glaze's "Aquadelic." Gorgeous colors! I'll probably do a manicure Monday on each of these colors!
You take 50% off of the red tags! So I paid $1.65 for the China Glaze and $2.00 for the Orly! Great, great deals!
I personally think you'll get a better deal if you go in store since some items may have been further red tagged reduce, but quantity and selection really does vary from store to store. Good luck shopping! :)
