Quoted from ThePinballCo-op:

I didn't do a pre-order because of the playfield issues early on. Then I saw how backed up it was so I thought I'd wait, plus I was in the middle of a couple other huge purchases. I figured I could get a NIB in April or May.

Quoted from TigerLaw:

I don’t want to feel like a sucker the day I buy something that is supposed to be fun, and an arbitrary one day 1k price hike would make me feel like a sucker paying....it’s not only about whether you can afford something or not, but it’s how something makes you feel when buy it and that extra 1k makes me feel like a sucker.

Quoted from Straight_Flush:

I was saving for a SE, finally Jack made a pin that I felt was affordable. Then he goes and raises his price 1k? Keep your pin jack. Hot wheels is a bargain @ 6300 free topper,side blades,shaker motor.

Quoted from Mrawesome44:

I can give you a couple good reasons people may not have gone in at first.
1.Playfield issues.
2.The huge backlog
3.No timeline for when people will receive games
JJP seem to love shooting themselves in the foot. This is just another situation where the backlash could have been avoided.
