Where to get empty cartridges?

[xKrazYx]

Is there anywhere I can buy empty cartridges for the M401 Pilot and the RN4081 NPRO?

I got some Black 401 carts on order.

I don't know about the 401, but I just bought some empty carts from Totally Wicked for the RN4081 NPro that I have. I ordered them Friday night, and I have a tracking number email now. Shipping, however, is a flat $6.99, so you might want to check out their e-liquids while there.
