In my experience if you sell them at a discount that is usually where people will take advantage of the cheap price to breed something potentially valuable.
When you give an animal away to someone you know and trust it's different and you do not have to mention they are het's for anything, not like it matters anyway since the person would be getting a pet, they could make a great class pet, first snake for a child (even with a low rehoming fee)
Few years back I rehomed a CG Pied we are talking when they were still pricey and high in demand, the defect was minor (underbite), I knew someone looking for a CG Pied with no intention of breeding and she was happy to get him, would have I sold it at a reduced priced someone would have seen this as a good opportunity to get into a project for cheap and I don't agree in building or breeding animals that are not flawless.
