Hong Kong is a Special Administrative Region, meaning its different from China. British left HK with the basic law, so HK can remain an International Financial Center, where trade is quick and trust worthy. And basing a shop in HK actually increases the speed. Cube retailers have to wait for Chinese manufacturers to ship out the products, then assemble it, and ship it to you. HK and China have direct shipping, and don't have to wait weeks for the ship to arrive. For your information, Chinese shops on taobao have already been selling it for 3 days, for around 65 RMB. Less than 10 USD. So before you say anything against Hong Kong, read its history. All mass-produced cubes (except v cubes and maybe calvin puzzles) are produced in China. Without the cheap production cost, all cubes would be the prices of v-cubes. So even tho its known for being non-trustworthy, give it credit for producing great and cheap stuff.
I have to admit HKnowstore has crazy prices.But shipping has never been a problem for me because of my geographical location.
