Have you used vat back deals and where you able to actualy get the vat back?

There's a laptop I found with a promotion from LENOVO it's £30 more than one I found of exactly the same speck by LENOVO but with out the vat back deal after vat removal it would be £75 less.
The clame must be after 21-51 days and in terms and conditions it says they can't be held responcible if tecnical isuse prevent me claming. So they basically have the power to legaly prevent me claming. I'm trying to figer out the likely hood they will or any other catches.

YOU can't claim back VAT unless you are a business and are VAT registered.

"VAT back" and "VAT paid for you" are misleading terms - the vendor IS NOT amending VAT, the vendor is cutting the price to produce what looks like a VAT cut.
