Website was easy to use I had some questions which were answered quickly and efficiently. I can't comment on the product as it's a Xmas gift for somebody
Item exactly as described. Posted quickly and well packaged. Great communication. I was sceptical as the price was so good but took a chance. Delighted with my purchases of Kodak blindbox key chain.
1st time purchase from A1 so was a little apprehensive having fallen foul of a spoof website recently. No need to worry though, purchased a Samsung S25fe for the best price in could find on the web at that time. Good communication via emails and delivery within a couple of days. All good.
The price of the phone wae very competative, the ordering experience was simple and effective, and tge delivery was faultless.(very quick and secure). Thanks.
