I phoned this company regarding an item that they were selling and seemed to be out of stock round the net. They told me they were out of stock but some were due in within 5 days, so I placed my order online. 5 days later the item was delivered and also 2 days before they sent a text and email saying when it was due for delivery and how I could change delivery date by way of a reply text/email. The night before delivery they sent another text/email saying during which 2 hr slot it would be delivered. All delivered when expected. Only downside is that it didnt note on their site if a product was out of stock and also didnt convey this during the initial email correspondence, therefore if I wasnt aware of this I might have wondered why it took 5 days to deliver, or if there had been a long-term stock shortage, why nothing was being delivered. So maybe thats something they need to think of including on their website/initial email correspondence. Otherwise very good experience and cannot knock them.
