And I've found that many sellers don't know much about what they're selling.
Often, the description of the size and volume is listed incorrectly.
Sometimes the cast iron is listed as "Lodge", when it's not Lodge at all.
Always look for a model number, and then do a search for that model number to find out the correct size and volume.
The model number should be printed on the skillet or pot. If it's not listed, or you can't see it in the picture, ask the seller.
Sometimes the seller says, "I don't know. I'm just selling it. The item description is in the listing. If it's not in the description, sorry."
I don't buy from those sellers. What are they doing, selling stuff they know nothing about?
And always search online for the current market price. Some sellers vastly overcharge.
A Lodge 8 inch skillet sells on Amazon for $12; There was a listing for that same skillet for $55.
Amazon is a great clue to what's currently on the market, vs. "rare" or "vintage." If you can buy it on Amazon, it's not "rare"!
Many sellers assume that the model number indicates the size of the skillet, or the volume of the pot. It doesn't.
Some of the most common listing errors:
A skillet with a #8 in the model number is 10 1/4 inches, NOT 8 inches. With a #10 in the model number, 12 inches, NOT 10.
A skillet with a #12 in the model number is 13 1/4 inches, NOT 12. A #14 is 15 inches, NOT 14.
Lodge does not make a 14 inch, 11 inch, or 7 inch skillet. Check that model number!
A pot with a #8 in the model number is 3 qts OR 5 qts, NOT 8 qts. Lodge doesn't make an 8 qt pot.
A pot with a #10 in the model number is 7 qts, NOT 10 qts. Lodge doesn't make a 10 qt pot.
A pot with a #12 in the model number is 9 qts, NOT 12 qts. Lodge doesn't make a 12 qt pot.
For camp ovens, the number on the lid is the inches in diameter, not the volume. A 12 inch camp oven is 6 qts or 8 qts.
Go to the Lodge website and familiarize yourself with their current products.
Since I'm nice, I usually send a polite message to the seller letting them know.
Ebay does have a refund policy for items not as described, but you may have to ship it back, and cast iron is heavy and expensive to ship.
So the take home lesson is, don't take ebay listings at face value. Research before you buy!
