I totally scored on colorful $9.90 denim, which they will alter for $5. Say what?! YES, $5! For denim over $20, the alteration is free! The price promo does not last long. I basically bought all colors, whether I liked the color or not because they could be gifted or whatever. They had $20 Merino wool v-neck sweaters, $40 fleece lined hoodies, and 6 pairs of colorful socks for $9.90. My bag was full and I walked home with a tote bag.
HOWEVER, do note when you plan on returning or exchanging go straight to the top floor, registers 13 and 14. Do not waste your time on the main floor only to be told by the register guide person that you need to go upstairs.
For alterations:
First, get your denim pinned in the fitting room. Upon checkout, ask the cashier to print you an alteration receipt, then keep an eagle's eye on the alteration drop off tables. One is on the right side of the main floor, which is basically a portable kitchen island type table, or on the top floor on the left side of the cash registers. They've quoted anywhere from 1-3 hours, which is really not bad for a store that just opened. I wore my new favorite, altered turquoise denim a few hours after purchase. Super happy!
So go shopping nowwwwwww!
