SOLO and International Paper are two large producers of most of the paper (hot cups) and plastic (cold cups). In fact if you have a Costco or a whole sale Cash & Carry in your area, they carry a large selection of SOLO and Dixie cups.
They do here, but I forgot they may not carry a lot of espresso or coffee related items everywhere else. However, here in Washington state, Seattle especially they carry everything under the sun related to this industry If they don't carry some of the items you want you might ask the management if you became a regular customer for those items will they order them in for you :wink:
The business Costco in Fife in Washington carries a ton of cafe stuff. If you have a business Costco by you they carry mostly business related stuff not personal related stuff that regular Costco carries. Even the regular Costco here in Washinton carries a bunch of Solo hot and cold cups. I use to live in California and they also carry Solo hot and cold cups.
