Ok, my current costco list seems to be:
large trashbags (Jen and I will need them anyway.)
assorted deli meats
assorted sliced cheeses
bread (probably 2 loaves of multigrain, unless someone wants something else)
2 gallon container of milk (it is Costco)
2 gallons of OJ
sodas
cereals
(I was going to get bagels, but I guess Rae has that covered?)
chocolate
fruit: (better/cheaper bulk source) probably
apples
clementines
bananas
regular sized: marshmallows, graham crackers
things we already have that I was planning on bringing and sharing:
Pita Chips
Pretzel chips
Lime nachos
Mango Peach Salsa
Hummus
Craisins
Dried Apricots
Peanut Butter
our Brita
Let me know if I'm missing anything obvious.
