Laugh if you want… I am.
I’m installing a new CPU today, was hoping to be flying by the time I’m writing this.
I cleaned the cooler block, cleaned the CPU lid, and squeezed some thermal paste on the block. Except that none came out. 
Thank you, Amazon, for having what I wanted in stock, with same-day Prime delivery.
oh… I know what you mean… same if you need a simple cable extension (e.g. cpu connectors) and your dealer (not Amazon) tell you: “in stock… needs ‘only’ 14days” 
Amazon has saved the day for me more times than I want to admit to…

Oh man, that would suck.
