I was nervous about ordering a phone from here as I hadn't heard of them before, but it was a fantastic price so took the risk, and completely worth it. Phone is fantastic, brand new in sealed box, and arrived fast after ordering.
Great value headphones, haven't set them up yet, they are a present for my mum. However the transaction was easy, the website easy to navigate and a fast delivery. Grateful thanks
I bought a Fitbit which was cheaper than Argos. It arrived on time by Royal Mail and is working fine.
I hadn’t used this company before but I did check their reviews. I would use them again.
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.
