PURCHASE DECISION HELP

So for Christmas i told my mom that maybe she can just help me get some stuff from my Amazon cart. So my dilemma is should I buy 5 regular priced dolls, or go for the gold and buy one of the more expensive dolls??? On one hand I could get more dolls but they’re regular dolls from the past couple years, OR, I could shell out extra money and get a single doll but it’s one I would have a hard time finding elsewhere
