I don’t know if $20 qualifies as expensive for some, compared to some of the other higher tier prices out there. But me as a buyer, my expectations wouldn’t be any different from any other price tier. When I buy products on the marketplace, I inspect the screenshots and/or video if available, check to see if the seller engages with customers, and read a few reviews before making the purchase. I’ve yet to find something I’ve found to be outrageously priced on the marketplace, and I’ve bought content in the $100-150 range before. I suppose if I had to say one thing that might put me off from a higher priced purchase it’d be a lack of engagement from the seller. But that’d only be for certain categories too, I personally wouldn’t need that for art but if I’d have a question about a blueprint product that’d be essential to be able to make contact and answer a few questions before making the purchase. =)
