SheIn offers its SheIn Women's Criss Cross Back Lace Crop Top in Orange or White for $13. Coupon code "INST33" cuts it to $12.28. With $1.90 for shipping, that's $6 off list and the lowest total price we could find, although we saw it at this price with free shipping in May. (Be sure to uncheck the shipping insurance box; otherwise, it adds 99 cents.) It's available in sizes S to L.
