H&M online shopping

[-kaffryn-]

I was trying to purchase two lush tops off the H&M website but it keeps saying my card details are wrong (which they arent) my card is a maestro but i can't see anything on the website about picking what card you are using like on other online shops. Does anybody know can you pay online by maestro card? I know you can in the stores :/

thanks! (hope it made sense lol)
