I fall on the side of simplicity and because it's 2024, most of your good customers will have certain expectations.
Shipping is free. Add shipping into the cost of the product and pay for it yourself using the service that works for you. People are interested in your product, not all the details around the task of getting the package to them. If someone asks, fine but make it easy and keep this out of the deal.
Only take Paypal. Enough people have it, nobody has to worry about "protection" and everyone knows how to use it. If you can't stand the fees, add the fee into the price and then pay for it yourself. if someone really wants your product and they have been banned from PayPal or they don't trust the "banking process" then it's case by case but yeah, after one or two of those....you'll find out. the more payment method you deal with, the less you know about them which likely means the know more about it than you do (and that might not be a good thing).
It's just my opinion but I think you miss out on good buyers who won't even look twice at a listing if they have to add up taxes and fees and shipping costs, etc. The fair price you list is OTD.
No sales to Canada, AK, HI, APO/FPO, or out of country. Too difficult and you shouldn't be shipping drones out of the country anyway.
I try not to sell my equipment once it is broken and beat up and looks bad so usually one good picture is enough and saying it is is good to excellent condition. if someone needs more pictures, that fine. Honestly, you don't need a bunch of pictures to prove to anyone your equipment is in excellent shape, they will be able to see it as soon as they get it. I'm stuck with a lot of accessories and extras because buyers usually want the drone and the primaries like the battery, controller. A bunch of filters and landing mats and strobe lights and customs cases, etc.....honestly, that kinda a turnoff if you appears you are also charging for those because they are used and that's more your style...not very valuable to someone else. Plus it eliminates the questions, can I get the drone without the [accessories] for cheaper which you'l have to admit it's the same price.
. A nice HQ image that someone can zoom in on should be fine.
These are just my opinions, take whatever works for you. I list and price to sell quickly so those are my guidelines.
