Hi,
What exactly did you buy?
For starting the fires, run to buy the Weber Chimney, which was highly recommended by Gary. Fill it up with the wood charcoal on top (not brickets) and loosely stuff newspaper under the bottom grate. Light it, go away and you have suitable coals in 10 minutes or so. Building the fire was my major obsticle, I always blamed it on not going to boy scouts. Building fires and tying knots, great skills not well covered in Girl Scouts.
Berger Brothers does accept checks; perhaps not out-of-state checks. A 40 pound bag of wood charcoal, not brickets, is around $16.
Peoria Packing I went to for the first time yesterday. They accept cash, LINK cards and there is an ATM machine on the premises. I bought almost 14 pounds of pork shoulder and a few pounds of hot links for $19.80, just to give you an orientation.
The meat room is kept refrigerator cold. All the meat is out in the open, no plastic, no packaging, no nothing. You are expected to wear plastic gloves as you move around. I saw cuts of meat I have read about, like pork bellys with or without bone, but never really saw before.
I was also advised the first 4-5 days of the month as well as just before holidays, they are so crowded they meter people into the place. Though at 7:30 on a Thursday, Gary and I were nearly the only customers.
Good luck you are in for quite an experience.
