Afection cost is roughly the same actually its either 417 or 418 per point on each item the differnce is legendary items obviously accumulate quicker because it takes 500common flowers to get the same as legendary lingerie the flowers sell for 1254 which times 500 is 627000 while the legendary lingerie cost 625500 so at most you would be pay 1500 more for the lowest item comparing to the highest item. The problem there is you have to buy 500 flowers to get the same as buying one item.
