Is yoobi a good site to buy from?

There's no need to chance it, I don't think they sell anything unique and are not non profit, so their items or similar should be available on more trustworthy sites. They might be ok but small sites/operations means small (possibly slow) shipping/service or even a part time seller. They look US based, but I am also reluctant to buy from anyone that won't say EXACTLY where they are.
