Our school has signed up for buy4schools.co.uk ie you buy stuff from various retailers through their site, get cashback and the school gets some too, but buy4schools (which seems to have a connection with parentmail) doesn't seem to generate much for the school.
I've done my Tesco shopping on it and have got zilch, and their customer service is rubbish ie they don't answer emails, so basically I'm trying to establish if there are other websites that operate on a similar principle but which might be better for the school ie in terms of generating funds. TIA.
