I need to ask a question and want advice

My friend and I are planning to go to Japan by the end of this year, and of course, because of that I want to save money, but knowing SH monster arts, they’re collectibles and won’t come back and will only be sold for more by resellers, so do you think at japan and specific the Godzilla store will have anything and I can save up more by not buying Shma or should I just purchase shma throughout the year? This is what I currently want and hope they’ll have when I go.
