There wouldn’t be tax on used items. The tax was collected when it was new.
Nice try.
The itialized part of my post, the part that says - I just had a yard sale and sold my lawn mower for $100. Who is responsible to collect the $9 sales tax from the buyer? was from TLittlefella's vanity article. I was quoting his material.
Either you intended your comment for TLittlefella or you are posting while on a crack binge. You should really go back to rehab.
I hope this helps.
