2 years with rc mushroom and rc mart.
Personally I went to rc mushroom and rc mart in hong kong. The shop are there, well, the shop look like a warehouse. Nevertheless, the shop are real, with real people working there.
RC mushroom is my favorite place to shop when I arrived in hong kong. Very close to railway station.
When you order for the first time, three things must be completed :
1. Scan your credit card and personal ID card front and back
2. Scan your credit card billing statements
3. Sign the order form ( mail as attachment )
After you complete those three, you can shop easier ( no need to repeat #1,2 ).
