For a limited time, Tilly's offers buy one get one 50% off all red tag clearance. The boys' tees, originally $16-$20, drop to $13-$15, saving you $3-$7 each. Your second item automatically deducts an additional 50% off the lowest-priced item in your cart, making them around $20 for two (depending on which ones you select). It gets even better with free shipping when you use code FREESHIP ($7 savings) at checkout. Plus, you'll get $10 in Tilly's "Moola" for every $50 you spend, to use on a future $40 purchase. There is no sales tax (except AZ, CA, CO, FL, NY).
