A few weeks delay is nothing at all, the turnaround time of the stuff massdrop is selling is still incredibly fast by most standards.
Normally as a consumer you're heavily shielded from these sorts of delays by large companies who plan turnaround times of months or years, any delay in one place is generally absorbed easily by changing timescales elsewhere. Massdrop isn't a high-street retailer, you're getting a product hot off the conveyor belt, the benefits of buying thingsthis way comes with potential downsides too.
