I'm just looking at Nucleus and for example this vendor I am looking at, it seems he had sample listings but it looks like he may have gotten too many orders cause some people said he was taking forever to ship it. Anyways, a couple of people said they got refunds but then they give him a 1 star review.
If you get a refund, shouldn't the vendor get a review that doesn't bring down their rating? What incentive is there to refund you if you are just going to leave bad feedback? Sure you didn't get your product, but you got your money back so there's no reason to give the vendor bad feedback.
And in this case, its a fucking sample listing, like jesus christ, sometimes you people expect a little much out of these vendors.
Edit: Yeah, vendors shouldn't have product listed that they don't have, but I guess some are just lazy or maybe their supply is running behind. Just don't think it should hurt their feedback if you got your money back or whatnot.
I'm gonna add, if someone TAKES my money in exchange for a product I want and they tell me they have, giving it back later is just an inconvenience.
