Yes, prices would drop. But the neopoints in circulation would be alot less, therefore, the price would be lower, but it would take alot more effort to make the neopoints to buy it since there are less in the market. It sounds confusing. But it makes sense. If you spent $10,000,000 on something in 1913 when less money was available, it would be worth way more money, but the actual value of the item didn't increase, the item did with inflation: Here's an example of what I mean. What cost $10,000,000 in 1913 would cost $21,434,417.07 in 2009.
i broke down and spent 3,250,000 for the stamp and background. *shakes fist* grrr, TNT-- this best be worth it.
