I know this is not a deal as such but it does involve nearly everyone who buys online and uses websites like this.
If you purchase a product online and ask for the whole order to be returned within 7 days the merchant must refund both your purchase price and post and packaging.
this is under the consumer protection distant selling regulation of 2000.
Most retailers will refund the product price but refuse to refund P+P. This is against consumer law. Confirmation can be had at consumer dirct.gov website or phone 08454040506
I know for a fact that most catalogues try not to refund you your P+P but under law they now must. You should phone their customer relations and insist on the complying with the distant selling regulation of 2000 or put it in writing.
I am also hoping the catalogue I use will go over the last 10 years of my account and return the hundreds of pounds in P+P they have ilegally kept.
Hope this helps many.
