Can anyone help me get the limited stuff before it leaves?

My friend and i just started earlier today, the game is super fun, but we missed the admin abuse and I can't afk with the device I'm playing on, so it's been difficult to get some things, and we saw both limited plants show up, but we couldn't afford them.

I only would want enough to get the limited stuff and I'll grind for the rest that stays, I don't want to ruin my experience by getting unlimited money right away like what happened to some in GAG, I just don't want to miss out on the Valentine's stuff.
