Self-promo plug - I've been working on https://MiniPCs.zip for the last few months, which is a kinda inverse concept - build a price model for Mini PCs based on their parts, and find the best possible deals - since these are like commodity items and prices change every day
right now we are limited with daily api calls. One way to support additional markets is to add data sources but that requires a monthly fee. This will be our next step.
