Along with the previously discussed FOMO aspect, I also had mentioned two other closely associated aspects to that - at least, by my personal experience - and ones that sound rather similar. One of them is now the subject of this post: "BOGO", short for "buy one get one". It may be that the relation of this aspect to the previous one (and perhaps the third, which will be discussed whenever) will appear rather superficial by way of that experience, but then there's a way of tying that aspect to Pokémon as I have done for the previous one.
Whether they're Pokémon fans or just ordinary ones, people will likely have heard or seen this aspect in relation to purchasing things. Essentially, it's a form of a discount where one buys an item and gets another one (of the same or similar kind) along with that item. Given this link, it becomes evident that the aspect is most pertinent for Pokémon merchandise, something that one could expect to buy one of and get something additional, although a few other purchases related to Pokémon might also qualify to have this aspect.
Looking at the current offerings on the Pokémon Center web site, there may not be much leeway in anything that might allow a BOGO offer to take place, but the major end-of-the-year festivities are on tap, and even minor BOGO offers could be offered then... and may have been in the past, though that seems hard for me to discover for one reason or another. Meanwhile, the offerings of current Pokémon games with paid purchases often have bonuses, especially for those who purchase the offerings for the first time, and selected offerings may essentially be a BOGO offer for those who know when and how to look.
In attempting to relate this to the previous aspect, it's quite possible that BOGO offers might stimulate a FOMO feeling because of the way they are often limited-time. That may be especially so if one doesn't know how long the offers have appeared and how much longer they might be around for. In that respect, at least some games per the above may have lessened the FOMO feeling by way of informing how their "BOGO offers" have been and will be around, but even with that, at least some of the feeling might persist.
Perhaps it may be hard at times to justify the presence or existence of BOGO offers, or things that can be construed as such, for Pokémon matters. Yet as part of dealings and transactions, it may just sometimes make itself present, albeit not explicitly. As subjective as the relation is between this aspect and the previously discussed aspect, explicating them, that link, and the possible connections to Pokémon may still be warranted, and it may just be the prompt for looking out for and not missing the next (form of) BOGO offerings.
