Was I fleeced? Bought a carpet for an irreguler shaped room, next to an underlay...

Bought a carpet for an irreguler shaped room, next to an underlay that be actually more expensive than the hearth rug.

They left the hulking ofcuts from the carpet (which come in one piece) but took the remaining underlie which came contained by smaller rolls and hence can be used at their next opportunity.

Should I return to the carpet shop and complain?
Answers:    If your room is 7m x 3.5m (at its widest) you be likely as not sold a 7m x 4m hearth rug. Carpets are generally 4m far-reaching in the UK, so you should hold been sold 28 square metres of hearth rug. The waste pieces are useless to the shop (it's a discomfort to get rid of them believe me), and they are distinctly your property.

As regards the underlie, it depends how much you were charged for. If they charged you for the 28 square metres afterwards you ought to have have the balance of the underlie. Check your itemised bill for full details though.

It's very adjectives for underlay to be more expensive than carpet, particularly if you enjoy paid below lb6 per metre for the carpet. There are tons of budget carpet, but not tons of budget underlays. Shops keep the prices of these carpet artificially low so they can upsell on underlay etc.

So find out exactly what you be charged for and take it from near. It's likely that they owe you a bit of underlie.
Yes, if you bought all of it that they brought to your house.
