Any sites have lay away??

Good afternoon,I am looking for a classic YSL Sac de Jour bag ,but I am looking for a site that does lay away? Do you know of any?
I bought an LV ALMA from Jesscia with [email protected] to compare it with my authentic one and got confused as to which is the authentic one. Needless to say, the quality and craftsmanship on the bags are phenomenal. Good luck to you!
