Hello there! I'm curious about how to get that amazing 25% discount at H&M. Could you please walk me through the steps to redeem this offer?

Additionally, is there a limit to the number of times I can use this offer? I'd appreciate any information you can provide to help me make the most of this great deal. Thanks in advance!
