I usually buy at least one from each race. They can be pretty expensive individually at times but I like the bulk buy option that was recently introduced… though they can be full of burst shot images.
I like to support the photographers seeing as they spend all day or all weekend standing about, sometimes in terrible conditions too!
One suggestion, and I don’t know if it’s possible as I’m presuming the photographers set their prices, but it would be good if after a period of time, say 1 year or 2, the prices of older photos went down. I doubt anyone wants to pay £7 for a 3 year old photo, but if it dropped to something like £2, some people might buy it for old times sake.
