These were posted over a month ago, but went out of stock. QVC have just received a further delivery of Get-a-Grips, just in time for the latest bout of cold weather. The QVC price for these is very competitive, as they do not profiteer from the high demand at this time of year. eg. These are £19.99 + delivery from an Amazon reseller.
I've just ordered a second pair as I find these make a big difference when walking in snow or ice. Reviews on QVC web site are also very good.
5% Quidco available to bring the total cost below 15 quid.
