Welcome to SaleHoo! It's really nice to hear very positive remarks from a new member:)
Personally, I haven't used BigBoxstore.com. They are one of our new suppliers, that's probably why they have no feedbacks or ratings just yet.
The first thing you can do is try and establish a solid line of communication with them. Inquire about the product you are interested in or ask them questions you have about their policies. Something like getting to know them.:) When you have achieved this, you can start by placing a small sample order and see how things go from there.
But if you still don't feel too comfortable, you can try browsing through the net and see if you can find anything negative about them.
Please be assured that we at SaleHoo screen our suppliers to the best we can, ensuring that each supplier meets our standards and is safe for our members to use.
If you have any more questions, please ask away. Cheers!
