if code die in 5 days I will change a new code for you
they all work when you first use them. as soon as sb realizes you carded them they kill them off. 5 days is not enough. i have had many codes i have purchased from other sellers die 2-3-4 weeks and even 2 months later. just had one die from your doppleganger LISA2015 after 10 days. you are probably the same person because s/he just disappeared and now you reappeared.
Is this a problem if you use the card as soon as you get it (within a day for example)?
as long as it is good you have no problem. check it online before presenting it to avoid embarrassment.
i rarely have had any die within hours unless they were bad when given out. it usually takes a day or so until SB gets a complaint someone is charging their card and buying these without authorization. i still have a few I got over the summer that are still good and a few that have gone bad in days or weeks or months. it' like gambling in vegas. i recently got a $100 card for $15 from a seller called LISA2015 on here. it lasted about 10 days. i went to buy a breakfast sandwich and coffee the other day and the card was rejected as "closed". it worked fine the first 9 days. i got my $15 investment back so i didn't lose $$. i'd bet 5cents this is the same seller under a new name because one disappeared and the other appeared which is how it usually works with these folks.
