I've placed, over the last year, 3 orders on Cookstore.
The good:
Everything that I ordered was received and was exactly as advertised on their website.
All orders received were in original boxes by manufacturers and well packaged, so that there was no damage in shipment
The very good:
I wanted to change the credit card number used for my order, and received a response back from the company within 24 hours.
I also noticed an item on one of my orders, that had not been delivered, had a price drop on their website. I contacted Cookstore and they honoured that price drop even though I had ordered it at a higher price.
The not so good:
On one order of the three, one item was backordered (a knife sharpener), even though the website said it was in-stock. The entire order was held up, but on contact with Cookstore they sent out all items immediately, and later shipped the knife sharpener when it came in-stock.
Delivery times are not amazon like (1-3 days), more like 7 to 10 days. Perhaps a trade-off you make in getting to choose from a wide variety of quality products at decent prices.
All in all, I'm a satisfied customer.
