The donations were all split up and distributed amongst the 50 grab bags, so they would be more or less of equal value with a few SURPRISES

That said, as I commented before, the items I alone supplied are worth $15 a bag, and knowing the value of some other contributions, I think that $15 is giving them away.

I would like to bet that if the contents of the bags went on ebay for example, we would get nearer $2000 than $750 (50 x $15).

Its supposed to be a fund raiser. If the price was $25 each, I would bet that 47 buyers would be absolutely delighted and 3 would be ecstatic.
