I think the original poster was in the UK, but they have tons of charity shops there.
Personally, I'd ask for the batting or gift certificates for my birthday/Christmas and just put the top aside till I had the money.
That is kind of what I do when I make a lot of tops because I'm not ready to invest in a roll of batting. I buy it by the 50 meter roll because I buy it wholesale.
