There are bond LEs available at MSRP or close to it right now. With the exception of Godzilla, recent LEs aren't selling for a ton over MSRP right now.
If you want to sit on one for 12 to 18 months, I don't think there's as big a pot of gold at the end of this rainbow as you think.
If you have 14,000 to sit on for 12 to 18 months, nobody would recommend the best way to make money off that is to flip pinball machines
Finally, there's been a handful of reports of people receiving bond LEs where the box is totally fine, but they open up the box and it's damaged. Not sure what your recourse will be if you wait 12 to 18 months for your buyer to open and find out it's damaged.

As I stated, Recent LE's, with the exception of Godzilla, are not. Bond, Rush, Mando, LZ, Turtles, AIQ are less than 3k over MSRP.

Those prices I think are more influenced by recent pinflation that occurred 2020-2022 and also stern now makes 1000 LE's. Prices track more with the economy and rising MSRPs, money that can be made in Flipping Pinball machines on LEs with the higher number produced and higher MSRPs is way less now.

The point I was really aiming at is that you have to get the game, store it, ship it, sell it on the market later etc... where you will almost always make more money simply investing that amount of money in something else without having to store, ship and sell a 300lb pinball machine.
