Build your gold reserves :P

im sure most high pot ppl know this, this ones for the new guys .

around market you can find yellows for 400k and vios for 1 mill, buy all of these that you can, then make them into supers. once you have some GB you can sell to groceries for 17 mill for super yellows and 20 mill for super vios, then begin process again

oh and also look out for normal exp balls that are still in boxes, some ppl sell them for like 700k and can be sold to groceries for 1 mill, happy hunting
