First time ordering from Geekbuying, quite shocked to see coupons actually working but price of item going up and ending to be more expensive than no coupon applied at all.

The Spunky Buds are already discounted in the flash sale. The way coupons work is that they'll revert to the original price before applying the discount. This is to prevent people finding loopholes to get stuff super cheap/free and quite a common practice with online stores 😉
I would recommend waiting out on the Spunky Beats as I should have a lower price on Monday. Or the Onyx Neo that is exactly the same soundwise, but lacks the integrated USB cable.
Store is legit. Just search in here you'll see many posts. Just as legit as Banggood gearbeast AliExpress. If code doesn't work then just don't use them.
Most of the time AliExpress or eBay will be cheaper so do compare.
