Sorry if this is the wrong area to ask this in. Basically, after 13+ years on Neopets, I have a rather large (for me) amount of NP saved up. I'm wondering if there are any "safe" items to purchase and let sit in my SDB in case I go on hiatus for the 80th time or something happens outside of my control, etc. I have roughly 50mil to spend. Not enough for the items I truly want, but enough to where I'm scared of the truly insane inflation rates causing me to lose out. Any input is appreciated.
