Ive been buying from them for years and have no complaints about their service. I'm disabled and struggle to shop in store so I've used them extensively.
I've had items not arrive and replaced very promptly. I've returned faulty or unsuitable items without problem. I've had disputes with intransigent Marketplace sellers and Amazon have always refunded my money.
The problems with them are several.
Amazon prices can often be beaten, not least because the postal costs they impose on their Marketplace sellers are high. You can often buy more cheap,y direct from an Amazon Marketplace Seller
