If it's available through any online retailer, Massdrop is generally pretty awful. At best it's $10 cheaper, at worse it's more expensive, and you have to wait forever for it. The only things I buy here are small-run mechanical keyboards and keycaps because you can't get those anywhere else.
I always compare the price + shipping here with other sites before i join any drop. If i find it cheaper elsewhere, i buy it elsewhere. Massdrop is a business.
