How much should I sell for?

[SoozyWoozy]

I need the space and so want a fairly quick sale - but how much should I try and sell my Britax Vigour 3+ for? It is in fantastic condition as I only used it for a few months, has the raincover and apron cover.

There are a few on eBay but some start at 99p, others listed buy it now as £150.

Help! :)

They don't sell for much on eBay. You'd get more if you're willing to post it.

I'm going to try £75 and see what happens...
