I'm looking for a way to intuitively display three price points for a single product - leaving the user to decide upon which they'd like to pay.
Generally, successful eCommerce sites feature a single, prominent 'Add to Cart' option, which of course works well for a single price point, but how can I intuitively display the differing price points, all without distracting from the ultimate goal of getting the user to checkout?
The only example I can give of this in practice is with CodeKit. CodeKit offers the user a set of radio buttons, but for me this doesn't work.
In this particular instance the item(s) being sold are tangible goods such as t-shirts, posters etc.
We're offering three price points, £23, £25 & £27. The product that the user ends up with remains the same regardless of the price point that the user selects. The first includes a donation of £5 to charity, the second £7 and third £9.
