Basically copy coupon, view price history or create e-mail price alert. What is best price?
Aliexpress
There’re some similar (or not) items on Aliexpress You can use link bot to get even lower price:
Banggood warehouse is located in China. As you can see I didn’t find any active coupon for this product right now… I don’t really know if this price is reasonable, coz there’s no price history in my DB.
Old coupons (from the oldest to the newest): BG589b2e, BG8FORMULAMX (probably won’t work, but you can try them out)
Price history and price alert
It doesn’t make sense to generate price history chart, because there is one price record which is: $31.99. 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)).
