I mistakingly purchased a inverter generator that I thought had 240v output. After carefully unboxing it, I found it only had 120v output w/o any option for combined 240v. ☹️ When I returned it the next day, the manager said there is a 20% restocking fee. WHAT?!?! This is posted nowhere that I have found! The back of the receipt shows "some" items may be subject to a restocking fee. How vague is that?!? The useless manager Michelle refused to negotiate anything less and said if it was an exchange, then she would wave the fee. Since they didn't have one that fit my requirements, I was now screwed. Thanks Michelle, you suck as a manager. Next stop... American Express to dispute the charges.
