This was £22.99 six weeks ago and seemed a good deal then but if you select the 64gb version without adapter and select Amazon as the seller it is £22.42. The important thing is that it's going to be a genuine product...too much fake memory going around these days. However, this won't be delivered before Christmas as stock is expected on the 29th so there will be a delay. A good deal if you don't need it immediately, as in my case.
