Notes:

30% raise and was lasted updated 4 years ago, this also took 1.5 years to move backpacks.

Strange Krabs:

"If you're raising and it's significantly higher than the current price, there's the argument that it will still be better than current"

Noblenaga:

"Probably ok to suggest since new price is more indicative of the price. Lemons has allowed this before."
