If so, I would go with seven2smoke over big bad amazon every day of the week
There is only a 2 dollar difference, you'd be helping another forum member, and only one of these 2 businesses takes bitcoin
If you have a look at the alieexpress link posted above it seems like he is paying about half the price he is selling them for and just ordering online to whatever address you provide meaning he is profiting $10 per powerbank for doing nothing you couldnt do with 2 minutes of searching
Anyways, If anyone want to buy this power bank
Contact me via PM.
Note: The price will be updated to 18 EUR.
