Hi Graham, to be honest I don't think that it really makes that much difference what the prizes are in a raffle because in my experience people tend to regard buying raffle tickets as the same as making a donation and they will buy tickets on the basis of how much they want to donate rather than thinking 'I won't buy any tickets because it's not a Samsung only a Digihome'.
If this is a one off or first time event it can be hard to predict what people will give but in a way you do need to be a bit hard nosed about this. At one of the regular events I help with, most people will spend £5 a head on raffle tickets regardless of what a single ticket costs, and whether that will buy them 5 or 25. Most of these events will attract 200 people so the raffle tickets usually raise around £700 because some couples will only buy £5 worth between them. If you think that the numbers will stack up in a similar way for you then the investment of £128 will be worth it.
But I think that depending on how many people you expect to be able to sell tickets to then if the main prize is to be a TV (and one which has a decent spec from the sound of it) then I would consider pricing the tickets at £1 each, £4 for a strip. It probably won't increase the total take very much because as I said most people will have a pre-set limit in their mind that they apply whenever asked to buy raffle tickets but it will reinforce that this is a decent raffle with the opportunity to win a high value prizes that is worth a great deal more than what you are asking people to stake. Enabling the people who will be selling them the opportunity to emphasise that surely the main prizes is worth a punt of £1 is a good tactic.
And a final tip, if the raffle will be taking place at some sort of event then a good selling point for the raffle is always to have a well laden table with the prizes displayed somewhere prominent as people enter eg by the desk table where any tickets will be collected. A well laden table, even if only of relatively small value prizes, will tempt people to buy tickets. After all even a £5 bottle of wine is a good prize if the ticket only cost £1! But having say a bottle of a decent malt, a bottle of cava or prosecco and a couple of bottles of table wine doesn't actually cost much but looks good. And after all, if he has managed to tap you for a TV then he must be able to charm other friends into donating a bottle from their own wine rack? It's amazing what does get donated when you ask. Most of us have been the recipients of an unwanted gift that is destined to find its way to a charity shop sometime soon but could be a welcome prize for the raffle instead. At one raffle we were given a boxed pair of Edinburgh crystal whisky tumblers that the donor was more than happy to get rid of because they couldn't stand ornate crystal! But the winner was absolutely delighted with them because they matched glasses she already had. Two very happy people and money raised for a good cause!
Different strategies work best for different raffle settings so I might be able to pass on few more tips if you can let me know whether this is eg a raffle at an event and hence there's only the opportunity to buy and sell at that event or whether it is one where tickets will be sold over a longer period before the draw takes place.
