OK, a couple of really important factors to consider with this type of purchase. Value is of course a big one and by value I mean everything from product prices right through to the level of customer service they provide to you, not forgetting things like good shipping times and inventory management structures ensuring that what is showing as available on your site is in fact available and no possibility that it is out of stock.
On top of those concerns, marketing is a big one. Remember, platforms like this make their money from the sale on and ongoing fees of maintaining your website, they aren't so much reliant on you selling their products, so many of these platforms don't care if you are generating traffic to your site or not. So you need to go in to these things with your eye wide open, knowing what level of marketing do they provide to generate traffic for you, if in fact any at all.
It doesn't matter what you actual sell, marketing is the key to generate traffic to even give you a chance of making sales. So look past everything else and focus on issues as outlined above would be my advice. If you can tick all the right boxes on those issues, then and only then would I personally show any further interest.
