ahhh my old favorite.
Years ago many here participated in this with a combination of banking and money order (MO) availabilities... Now those times are history (as is the time of Charter One gift cards) but thinsg can still sometimes be found.
I find a few supermarkets such as Shaws do in fact sell em, but you may find their highest MO amount to not be worth the hassle any longer. If it is $1,000 I may do it. If it is less, it's really not worth the hassle. Nor are most of the fees these days to buy those gift cards first.
we shall see!
