I've had 4 packages ship for orders in the past year. Two of which have been outright lost by FedEx. Drop's customer support has then made it seem like they were doing me some kind of favor by replacing the lost items and not just taking my money without me actually receiving anything. Now one of my packages, shipped to the same address as the others (which hasn't changed), has a FedEx delivery exception because the "address or apartment/suite number is wrong." And as always, FedEx won't talk to me about it at all, only Drop.
As I've done a number of times now I've fired off a Drop support request into the void and now I'll wait to see what response they'll give me. Hopefully they'll take care of this as they have in the past, but it's aggravating that I end up having to contact their support team with essentially every order I make. Especially given that they refuse to provide a phone number (though I can understand why if other people have as many issues as I've had).
At this point I have one last outstanding order with Drop: the awesome looking Sennheiser 8XX headphones. Given the shipping issues I've had I made sure to pay for UPS shipping rather than FedEx. I'm even going so far as to have them shipped to a different address in a different state. So, if there's still issues after going to that extreme, I'm just going to be done with Drop. Everything I've ordered from here has been awesome, whether it's been for audio or mechanical keyboards, but it's just not worth the hassle.
TL;DR: I really love this site and what they sell, I really do. But, I have had constant issues with their shipping & customer service. So at this point if I end up also having issues with my Sennheiser 8XXs I'm not going to be ordering from here again.
