Epi Pochette Strap?

Hi, have any of you ladies had to replace an epi pochette strap (or any pochette strap)? Will LV sell just the strap? I have a pochette whose strap has seen better days and I'd like to get a new one, but I don't know whether to try LV or keep an eye on eBay...

Thanks in advance! :amuse:
Louis Vuitton will just sell the strap for the regular pochette straps, I think they were around like 30-40$ ? I'm not sure about the epi pochettes !
