From your location, it looks like you are in Ohio. Not sure if you have a Meijer store nearby, but I saw they had a few racks near the Christmas area with fall/Thanksgiving tablecloths for 30-50% off. They had both cloth and paper ones. Other than that, I saw that Target had a few, but I didn't see any on sale.
Hope that helps, even a little.
Look at Kohl's they always has specials on tableclothes. I use a plain tan tablecloth then I decorated the table with silk fall leaves that I got at the craft store along with a couple mini pumpkins.
If you can't find anything, hit the bed/bath section of Target or Walmart and find a flat sheet in a solid color that is close to the size of your table. Put the sheet on the table as the tablecloth, then use some fake 'silk' fall leaves scattered in the middle of the table with a bunch of candles in the center (or some other sort of centerpiece)
Target had "holiday" cloth table cloths on sale starting at $9 and they have a $3 off coupon on their website (or they did last week, not sure if it's still there). Most of them are more Christmas-y colors but one color they had was gold, so that would work for T-day.
