Most economical vBucks (USA NA)

Was hit by the contraction of the Tech field, now making less than 50% of what I had made as a Software Dev after a year of unemployment. Not destitute, tho definitely missing the luxury of not having to be on much of a vBucks budget as in the before time

So, any austerity minded folks have any tips for the most economical way to buy vBucks? Currently still subscribed to Crew, so truly meaning just buy vBucks outside of Crew/BattlePass

edit: JFC if I wanted a lecture on financial priorities, I'd have posted over in r/povertyfinance -- if they don't ever go on sale or there's not an avenue for discounts, NBD -- doesn't hurt to ask tho
