If you have unwanted Christmas presents, then Play.com's online marketplace, PlayTrade is offering to help you offload them.

There are tons of services that offer the same - and that's not even taking into account eBay's clout, but Play.com is offering free exposure to its 11 million audience this month.

The special offer means you can try out the service for free this January. There are no commission fees to pay on your first five sales, so more of the money you make goes straight into your pocket.

And, unlike other marketplaces, Play.com says it never charges an up-front listing fee so you can list as many items as you want without paying a penny then and there.

Check out the service - and the small print for the offer - here and check back next week for more Daily Tech Deals.
