Is there a good place on line to buy 16 oz clear plastic cups.I have been to every store within 30 miles.Rex

Walmart has 16oz clear plastic cups pkg'd 50 for $1.98 here
There with the disposable paper plates.

Been to 2 walmarts here, no clear cups.

My wife got me mine from Kroger for $2.49 for 50ct.
Do they have to be clear? Consider white or blue?

You can also buy a soldering iron on ebay anywhere from $5 to $10. Making poking holes very easy.
Just where a mask to cover your nose and mouth so you don't breathe the smoke from the melting plastic.

I got some from Kroger AKA Ralphs too!  50 ct.  I like bigger sizes better, and I got 20 oz at Smart & Final.

In Florida, we get them at Publix.  The Dollar Store has them, party supply stores carry them, Walmart (mega stores in the grocery section, and you might be able to buy some at Starbucks if you frequent one.

The soldering iron works great for making the holes.  If you don't have one, you can use a butane torch to heat large nails as well.

I've use them in blue and orange when clear weren't available. They all worked well.

Food Lion and Sam's Club.16 oz cup fits 3" peat pot.

Just about anywhere that sells disposable paper/plastic ware for food.  As for the holes, I uses an awl to puncture the holes,  Mine has a short handle so I did 3 at a time from the inside ( for the bottom ) and singly for the sides.  I did about 10 and it took a few minutes to get my groove.

This time of year given the holidays, all of my supermarkets, and drug stores stock 16 oz plastic cups

I've gotten the 18 oz size at Dollar General and several drug stores.  I use a drill press with a 5/16" bit to make the holes.  Turn them upside down and drill a stack of 4 or 5 at a time to keep them from collapsing.  No fumes for me--I work in the chemical industry and my lungs have already had to filter more than their share. :)
