I use it out of laziness. Despite all the shit they still have great customer service. About a year ago I ordered a £150 multi-tool and they accidentally sent me a £200 reciprocating saw. Due to a complicated living situation at the time it would have taken me about 6 months to send the wrong tool back so they just said I could keep it and refunded me so I could buy the other tool again.
The other thing I like is that I’ll just see a price and buy it easily. I’ve often shopped around and found something cheaper but then the whole purchasing process is terrible. They add on a bunch of extra costs, then make me create an account, then add on more costs. By the end I could’ve paid less and got it quicker from Amazon. Not always the case but it happens often enough that I will just go to Amazon half the time.
But I guess the main reason is that I hate being forced to create accounts and so many shops require that for no good reason.
