Actually, this store is a good thrift store. There are lots of items, and a friendly staff. The above reviewer is obviously an amateur at thrift store shopping. The "pencil" you refer to is called a China Marker or Grease Pencil. These are used so the plates are not damaged by forcefully applying a sticker with a tagging device, which may ruin china or porcelain. Yes, WD-40 will get it off, and Yes, the WD-40 will come off in the dishwasher. You were going to wash these before you used them, right? There are TONS of clothes, and misc items to be perused!
edmond people drop off good stuff but the workers seem to think since it's edmond they will charge more, but HELLO I live in edmond, not every person here is rich, If I was do you think I would be shopping at goodwill, my point is a lot of items are over priced. I personally pointed out some items where more than the walmart sale price.
There are some cute things in this store (like any thrift store) but charging like $8.99 for a worn out Forever 21 top is absurd. Plus, they never have specials ...just 10% for old people on one day of the week or something. way too expensive. I'll stick with goodwill
