Is it a good idea to use BillMeLater on eBay?

[Ayu]

I always go shopping on eBay and Amazon a lot, so there's this 4G T-mobile phone that I wanna buy that's $150 right now I only have $46 dollars on my card, but in about 2 or 3 days I should have the money for it and more. Should I use BillMeLater to get the phone? cuz that's the last phone the person is selling for a good deal. Is there some kind of catch if I use BillMeLater ?

I have been using billmelater for several years. It is basically a form of credit, but a lot of items have 6 months no interest through billmelater, so if you pay properly, you do't end up paying any interest. I just bought plane tickets to St. Martin through it for a trip in March. I don't have to pay it off until the end of April. I have had no problems with it.
