I was very lucky to find an Ultegra crankset with the correct size arms at one shop, a set of brake calipers (rim brake for me) at another, and an Ultegra Di2 'upgrade' group, with levers, derailleurs, and wiring online, shipped from England. The bike ended up costing more than I had wanted to spend, but I have to admit, I'm sort of glad things worked out this way.
LBS has zero new bikes to sell. He's only open 3 days a week for repairs. Luckily, he was able to get a contract with the city to maintain/repair all the rental e-bikes used at the city bike path to keep himself in business.
I had an old, heavy, steel bike (8 speed Claris) that I had been using on a trainer with Zwift. I put it up for sale on Craigslist, it was sold within 15 minutes of placing the ad. It's crazy out there.
