Just wondering whether you’re maximising takings by having the same £5 price across raffles for items worth everything between £500 and £5k.

I’ll guess entering any raffle has the factors of a) contributing to a cause, b) chance of winning something you want but could buy, or c) something you couldn’t/wouldn’t otherwise buy. The right combination of these appeals enough and results in a purchase. There’s also how many people someone thinks might enter, which might balance things out for perceived value of buying a ticket.

I expect someone will have done a PhD on raffle ticket pricing.

Raffall shows me the number of entrants for past draws (only after they’ve finished?), £5 for 1 in 1053 for a £1200 Cotic Solaris frame, £10 to Cyclorise/Ukraine for 1 in 686 for a £6.8k Revel Rascal. Both were unlimited entries but notice that the former raised 4.4x the value of the prize, while the latter only did 1x. That’s despite Ukraine and a complete bike both being more widely appealing vs. the STW server payment and a bike frame.
