I just did some digging on Best Buy and Amazon for sales, but mostly came across larger models or models that were MediaTek/Snapdragon (the chrultrabook team almost exclusively works on intel devices).
I’d say your best bet is to go to the supported devices list, and Ctrl + F for ‘13’ or ‘11’ to highlight the smaller-sized chromebooks and then check to see what’s available, or to jump in the Discord and pose the question to those in the linux channel
