The prices of the Heirloom decks in paper aren't budget at all. Using the original price limits of 0.05, 0.1, 0.2, 1 in MKM gives an average deck price of $30. It's more accurate to use higher limits and see the price trend instead of the lowest price so there's less fluctuation in price. That's why the limits are 0.2, 0.5, 1, 2 looking at the price trend.
