At the end of the day the game has to make money and I'm sure everyone earning thousands of gralats from gifts they got for free from other players kind of limits the amount of gralat packs they may purchase around this time of year. One Christmas I was elated to see that I could sell enough of my useless furniture to buy a custom head or body. What normally costs $4 for a custom body or $8 for a custom head was free. I do disagree with Christmas items from previous years being marked down to one gralat (not sure if that's the case though). If the option was available to sell for hundreds of gralats for those furniture items they should stay that way because the rule wasn't implemented at the time the presents were opened.
