Um, not necessarily. It depends on the rarity of the varient, not just in the US, but in the hobby and in the wild. What I mean is that lacerdae are very rare in the US because Japan and other asian countries are willing to pay top dollar for their fish, that's one level of rarity. Then there's also the issue of their availability in the wild and whether or not the wolf is in an area accessable for capture. So there's different factors that will add up to the rarity of the wolf. Larger wolves don't ship very well either. Most of the time when they come in, they have really bad ammonia burn and torn fins and usually come with some parasites (like fish lice, etc.). All these factors add up to the price of the wolf. But, sometimes the bigger fish are hard to sell because not everyone has a tank to accomidate a larger size wolf. That being said, you'll get the most for your money buying a larger wolf that's in good condition. The smaller ones are a lot harder to come by because they are a lot more manageable in size and the price is cheaper, so when they are available, they aren't for long. Sorry I know I probably made this confusing, but there's a lot of factors that go into what's available and why. I just tryed to cover all basis for you so you have a general overview on the subject.
