everything below is UK but if it works in the UK then it obviously works in the USA.
jd sports - partial - i think full is possible (sign declaration form)
asos - partial but full is possible
footasylum - DOES NOT WORK
nike - only done full twice
hollister - partial - i think full is possible
H and M - partial - i think full is possible

zalando uk - partial - full is possible (sign declaration form)
versace - partial - don't know if full is possible because UPS is a carrier you don't want to mess with as i have heard they come to your house.
SCOTTS MENSWEAR + SIZE (i failed these 2 because i did them all at the same and they caught on to me, but essentially, JD SPORTS, SCOTTS, SIZE AND TESSUITI are made by the same company: JD PLC so literally the same process for refunding all 4 of them are the same, partial, declaration form, replacement then refund)
i am looking for a comfirmation on whether topshop/topman works. If you need help with refunding any of the above let me know on skype.
