People often buy objects and underestimate the routines attached to them.

The picture in your head at the register is of the object doing its job. It is never of the storage, the cleaning schedule, the special cable, the annual service, the moving day. Objects arrive with routines attached, and those routines are invisible right up until they are yours.

Try asking someone who already owns one what the annoying part is. They will tell you in about ten seconds, and it will be something you never would have imagined. That one question, asked before rather than after, will save you more than any discount.
