The moment you drive a brand new car off the lot, the resale value has already dropped significantly. Less so with a used car, but still, depreciation is a given.

With shaving equipment, many of us sell off things... razors, brushes, etc after (usually) mild usage. Countless times, though, sellers ask to get back what they paid for the item. Some even try to recoup shipping and paypal fees.

I am not talking about discontinued things or razors that are hard to find. Just the usual stuff.

I am just curious as to what people think is the acceptable cost of being able to experience a particular razor, brush, etc. in terms of % devaluation, ie, how much would you normally mark down an item after trying it out and deciding to pass it along?
