After searching for many many hours looking for the latest Ben 10 action figure toys, and being very tempted to pay the £8 to £16 + delivery costs that some Ebayers were charging for the extremely hard to find figures I managed to find a DVD/CD store selling them.
101cd.com mainly sells Music and films merchandise but (if your quick) you'll get:
Metamorfigure - Greymatter!! (sold for upto £16 recently on Ebay)
10cm Petrosapien Bounty Hunter
10cm Ben Tennyson
....all at £4.50 with free delivery - I believe it's also 6% back with Quido too.
Like I've said, it's near impossible to buy some of these (especially at £4.50) and worth getting them now before they sell out.
Please, please don't buy in bulk as I'm sure many parents are struggling to get a hold of these.
I ordered them a couple of days ago and have had confirmation of dispatch - so they have got them!
