Reminds me of the time a couple came to the Lexus Dealer for a problem with the power convertible hardtop. "It won't close...it's stuck open." they said. We whisk the car into the garage area, as it is just starting to rain. We play with the manual release lever a few times, and press the power top switch a few times.
I'm at the driver's side rear of the SC 430, holding my clipboard with the customer and car information. The trunk lid lifts slightly on one corner, and everything jams again. I peek into the little gap...and call out: "I think I found the problem..."
"...they went to Costco."
Moral of the story is that you may save $5 buying 16 rolls of paper towels, but you lose $1000 if you forget it doesn't fit in your car properly.
(Yes, a true story.)
