Banggood ($9.59)
Banggood warehouse is located in China. There are no active coupons for this product, but the price is pretty low isn’t it? Well, is it a good price anyway? I don’t know if this is a good price – number of records in my database is too low!

Price history and price alert
It’s a new item in our database, so I can’t create price history chart. We have saved this price in database: $6.99.
You can set price alert (for Banggood and Aliexpress (only if product name will be the same as on Banggood and I will post it on social media though, so it’s more like Banggood price alert)).
