Did you not research it beforehand?
There are diminishing returns on the amount of XP traded in. The more you trade in, the fewer points you get per XP after a certain point. It even tells you how many points you will get per trade in, so it shouldn't come as a surprise after you have sold your XP.
Like all shops in RuneScape, the cost to buy is more than the amount you get when you sell, so you were always going to be worse off.
Yes, a 1:13 ratio is very unbalanced, but this must be because you have traded a lot of XP from the same skill or two.
