Lots of options, but user should know this before buying:
Keyboards from them are overrated and overpriced.
Keycaps are decent quality (not the best feeling if the set is a non-GMK option)
They do have great deals for Holy Panda switches occassionally.
I highly suggest buying from them during sales, and their shipping times are fairly quick, longest wait was 2.5 weeks

Drop is a good company to help get a foot into the world of keebs, but as you go further down the rabbit hole, drop doesn't have the widest selection, prices are on the high side, and they are at times unreliable.

Here are the items that I bought from Drop in the past:
- GKs Matcha Dye-sub Keycaps
- Sennheiser HD6XX Open-Back Headphones

I had a smooth experiences in both orders, with the latest turnaround being a month.

The products are decent-quality, and I daily drive the headphones. They were excellently packed, and decently priced compared to similar products.

I don't mind the pre-order model, I'd just prefer if they stick to that instead of limited-quantity group buys going forward.
