Old Mill Antique Mall

I really don't know if they provide such.

The business phone number is listed

Yes

Would say no simply due to narrow aisles and breakables

Make

If any of their vendors sell stamps, they can probably put you in touch with them to get your questions answered. There's also a guy on US 1 not far from Barn Yard Flea Market that sells stamps and coins. He might be able to help you. Can't remember the name of his shop but it's on the left going out of Columbia towards the Barn Yard. He's in a really old brick building. He has a sign out for coins, stamps.

Not sure what's there now, but I know they have had them and will surely have them again

Yes I have purchased items many times. Collectibles, vintage kitchen items, old books, knick knacks, etc.

It depends on how much square footage you want. Once you've gotten what was available, typically, your rent is paid by your sales if you have any. You won't get paid anything until you sell more than your rent. This place is pretty popular, so their rent might be different than other places. Still, it is probably reasonable, but more than you would pay for a storage unit of similar size to the space you get here. Doesn't hurt to shop around, though there aren't as many places like this as their once was. Also, keep in mind that Old Mill does sales that I believe all venders are required to participate in.

May I give my cell number for when she returns maybe give me a call???

Yes like Jack Williams said the warehouse would be my first stop.
