How to use "letting go"?
Can I say:
A) I am letting go of my printer.
B) I am letting go of my printer as I do not use it anymore.
Does "letting go" has the meaning of something that the seller does not need anymore and it will let the buyer feel that the seller would be selling it cheap because it seems useless to the buyer?
Both A and B are OK grammatically. Perhaps B is a little redundant in that presumably you wouldn't be letting it go if you were still using it.
I don't think "letting go" necessarily suggests that you would sell it for any small amount, it just means that you don't require it any more for whatever reason.
If you said that you were getting rid of it or ditching it, then the buyer might be looking to pay a fairly low price.
If you're writing an advert you could take a different approach.
"I have an Acme 2000 printer in good working order for sale at $150 or near offer"
… or something like that.
