What our merchants say

“We were actively seeking ways to put more purchasing power into our customers’ hands by offering quick and easy alternative payment methods that are available everywhere they shop, without slowing down.

An easy and intuitive integration meant the new rue21 checkout online and in-store, could be up and running without any technical headaches to slow our momentum.”
