Yeah- there may be some vendors who would try this.
Customers are pretty savvy, though, and likely will not wish to do business with someone who is being a jerk like that.
As much as it would be great to be 100% jerk-proof, it is impossible. People always find ways to do cruddy tings like this and try to avoid fees. You’ll have to police your site some- because as son as you think you have found all of the loopholes, inevitably someone will find another one. 😉
I do not think we have plans to include this as an option in the future, no. I know it has been brought up before. We appreciate the suggestion, though- and I do understand your concern.
In all fairness, though- from a different perspective– imagine the view of the legitimate vendor (this will be the majority). Let’s say you have 1,000 legitimate vendors who are selling products that require a rather hefty shipping fee to be shipped overseas (or even domestically). They sell something like clay coffee mugs- heavy. Should all of these honest business owners be penalized and loose revenue from their sales because one idiot may come along every one in a while and try to scam your marketplace? Food for thought… 😉
