Cheers guys.
They produced a proper looking website and even a VAT invoice with VAT number on, so at the time I was like "checks out". It wasn't till after the money left my account and they went cold that I dug deeper and saw many parts of the website didn't link to anything and the VAT number was for a different company (was also slightly wrong, used a non-existent prefix for a UK business) and when I looked at the telephone number (which was listed as a mobile) it was actually a Glasgow area number (land line) that goes straight to answer phone.
Needless to say, make sure you check very, VERY carefully or, as mentioned (and reminded several times by my bank
) use PayPal goods. Yes, 5% fee seems annoying but if I'd of paid the fee (about £192), I'd of been so much better off. £3200 better of to be exact...
£192 or £3200... I'm doing a maths degree and I still didn't work that one out!
