I bought £10 credit on Boxing day for this offer, and never got an email. I only got round to sitting down to write an email to them yesterday, but it turns out that they'd given me it all along, just without telling me! I made my first calls yesterday, for free. I think I'm going to use this quite a lot now! Hopefully in the next six months they'll get round to sorting out a UK subscription which gives you free calls to UK landlines for a fixed price.
Just another Skype related thing, I topped up £10, which cost me £11.50 (£10+vat). Looking at the costs of calls it gives a price then another price including VAT. Seeing as though I've already paid £11.50 for £10 credit, the amount taken off that £10 would be the price without VAT, won't it? (Obviously for calls not covered by the Talk for Britain deal).
