1 - US dealer has no stock. Never had. Hardly ever will.
US dealer ONLY collects and processes orders. All orders to the US are sent directly from China.
2 - There is NO shortage of bases. Neither there is of grips. Neither, of base+grip sets.
US dealer sometimes gets late with site stock updates/refreshing, hence the goods appear "out of stock". It does damage our reputation some, as it contradicts to what I have written above but little we can do about it, at least now (we're working on it though).
Now, to the point. If some goods appear out of stock in USA store, chance is pretty high it is only due to technicality. Contact the dealer, and ask him to update the shop information, and place the order. We will ship it out within 36 hours.
