I have checked all old coupons and price is $18.99 for HILDA 3.6V Cordless Mini Drill with 45pcs Accessories (in Banggood). You can create price alert here, copy coupons and view price history. You probably want to know what is the best price?
Option C: 1PCS MINI DRILL + 45PCS Accessories
Latest coupon and price update (UTC):
Banggood ($18.99)
Banggood warehouse is located in China. I couldn’t find any coupon for this product on latest product update. But wait a sec… Is it a good price? Hmmm, price is higher than average (which is $15.49 right now), so better set price alert down below…
