So funny you said this, I had a really awful experience with them, however it was an order placed over the phone. I specified that I DESPERATELY needed the item by a specific date (they said they would rush it to me) because I had to be out of town for work, and it didn't come in time, and I had to cancel my work trip which was a nightmare. I called and spoke to a manager and they were semi-apologetic, but I refused to leave for work without the bracelet because FedEx hasn't made me sign for ANYTHING this past year (probably because of the pandemic) and I didn't want to leave a $7,000 piece of jewelry on my stoop for a week, unattended.
Normally I wouldn't be so upset but I talked to several people to specify how crucial the timing was, and offered to pay for express shipping and was assured it would be there on time, only to have a nightmare of a hassle trying to track down the package from Fed Ex, to find they sent it with regular shipping.
