how much could i sell a used scratching post for?

i was wondering , i wwant to buy my cats a new scatching post, but because my apartment is small i have to get rid of the 2 i have now. how much do u think i could sell a used scrathinc post for? 1/3 of the orginal price ? the one i got now cost me $158.00 and it has 3 tiers and 2 feeding bowls attached to the 2nd tier (sort of like a feeding platform- the bowls come out for cleaning) its a bit frayed around the poles and i've had it for less than a year. its about 4 feet hight. i was thinking %50 bucks?

i also have another one which is a plain scratchng post with a flat top which is about 3 feet high. it has a hanging bell...i was thinking $20? i brought it for $100 ( i also think i got ripped off for that one!)

what do you think is a reasonable percentage of the original value i could sell a used scartching post? it would be such a waste to throw it away!

I'd buy the three tiered for $75.

Though the only hitch is that I live up in Port Hedland so it would involve sending it. I will pay for postage and handling or freight if need be. I can't find any good quality or vaguely interesting cat posts.

If you're interested, just send me a PM.
