I have no idea why would you purchase this stabilizers in Drop but only because you have some rewards credit.
Durock plate mount stabs are 8 bucks on Dangkeebs, and Cherry clip-in are at 9.99 bucks in Cannon Keys. Lemme reiterate, to my perspective and if you live in the US (I don't know if Drop ships cheaper to other countries) there is no reason to buy them here BUT 1.
