Hi,
Can you give me please the shop link?
Thanks
OP which country are you from? I'm surprised you don't know about amazon or newegg, this stores are the most popular around the world
1. Amazon.com
2. Newegg.com
3. Innosilicon.com
4. Bitmain.com
You can buy from aliexpress too but it's not as safe as the websites I listed so make a move and drop your feedback here later
