"Pre-tax increase campaign" ~ until 9/30

【9/20～9/30】 Just before the consumption tax increase, rush! Cysterra (SysTrade) campaign ongoing

The above EA developers are offering a limited-time sale of valuable bundled products.
There will likely be tax increases again in the future, every few years,

this time a campaign limited to until 9/30.

“Until now, I’ve never purchased any of the EA developers’ EAs～”
this is a chance to try while it’s a good deal.

“Incorporating EAs from various developers into your portfolio”
even that itself provides a risk diversification effect.

EA developers are human too, each with their own logical quirks.
If you always operate the same developer’s EAs, bias will inevitably occur.

Why not take this opportunity to consider it?
