SheIn takes up to 34% off a selection of its women's swimwear. Even better, cut 33% off via coupon code INST33. (Note that the coupon discounts the original price, so some items may already carry a greater discount than 33% off.) Alternatively, drop 35% off orders of $99 or more via code COME35. Shipping adds $1.90, or get free shipping on orders of $19.90 or more. (Be sure to uncheck the shipping insurance box; otherwise, it adds 99 cents.)
