Well logistics is a very complex arrangement. It’s possible that in your two scenarios, there are two sellers involved. The one who could get it to you fastest didn’t have any stock the first time you bought, so they weren’t an option. Then later they had some inventory come into stock, so they were an option the second time you bought. They can deliver to you so much faster than the other guy that they actually beat him despite his head start. Maybe they’re right around the corner from you, so to speak?
Amazing fulfills a minority of orders now. It’s all 3rd party sellers and your experience is contingent on them, their prices, their inventory, their seller rating, and many other variables in the system that we can’t even see. Fluctuations will happen and it’s probably not Bezos trolling just to get his jollies.
Yep hate this. It never errs the other way. It’s always over optimistic at the time of sale. Sometimes it really creates a problem if speed is what you need and the whole reason you chose that product with those options.
