the thing is, don't let the price stop you. if you really want it, go for it. otherwise, your heart is going to keep coming back to it.^___^ and also you should factor in the fact that the price of b-bags has kept rising...and you might end up spending even more in the future.
on a personal note, though, I'd rather spend that money on a PT....
i'd like to share some advice that my friend offered me. I think it's by far the best for buying b-bags: just buy whatever bags that your heart desires..they won't be the last bags that you buy....you'll buy more in the future anyways!
