I can order packs of 100 $2 anytime of the year from my local Wells Fargo branch where I have my accounts. I always ask for new but they get packs of mixed, meaning some used, some new mixed in with all the bills. I cull through them taking out the newer bills...most with consecutive number runs....and give them back the packs. But around mid-November they start their Christmas ordering and you can order brand new consecutively numbered packs of $2 bills, which is what I do. I always keep a couple hundred on hand to use throughout the year to charge my Starbucks card, use at tips, pay for small items costing a couple bucks. I like to try to keep them in circulation as I have always liked $2 bills. If I am lucky enough to find a star note or some nice 1976 or 2009 bills in the circulated packs, I keep those and stash them. If they are really thrashed I just leave them in the packs.
You're right. I just walked to my CU and bought a bunch of $2s, new bills in sequential order. She was telling me how she uses $2s to buy coffee at Starbucks because it's $1.98 and he just hands them a $2.
I usually spend most of my two dollar bills, the people at the check out line have either oh wow or are they real all the time.
