Bulk Tobacco Price Increase of 25% in Less Than 60 Days -- Why?

I have been a member of this forum for nearly seven months; and even though I have not posted very often, I do check-in at least once every day to follow the current threads. Today is really the first day that I have been moved to post some information that I find troubling.
I went to P&C online today to place an order, and I discovered that prices for some of my go-to McClelland bulk tobaccos have increased nearly 25% since I placed my most recent order in May. I recognize that P&C had a 10% discount on my McClelland orders in May; but even after accounting for the 10% discount, the same tobacco order has increased from $121.12 in May (i.e., $133.23 after 10% is re-applied) to a whopping $166.40 today (2 July 2014). That is an increase of 24.89% in less than two months.
My question is "Why"? Is this being driven by the fear of the new FDA regulations?
For those who may be interested in the specifics, here is a breakdown of the orders (showing May prices WITH an adjustment for the 10% May discount applied):
McClelland #2020 -- 8oz -- $22.53 on 09 May -- $28.16 on 02 July

McClelland #2045 -- 8oz -- $22.53 on 09 May -- $28.16 on 02 July

McClelland #2050 -- 8oz -- $22.53 on 09 May -- $28.16 on 02 July

McClelland #5105 -- 8oz -- $22.53 on 09 May -- $28.16 on 02 July

McClelland #5110 -- 16oz -- $43.12 on 09 May -- $53.76 on 02 July
Total -- 48oz -- $133.24 on 09 May -- $166.40 on 02 July
I am a loyal customer of P&C. I have been very pleased with their services. But what can possibly account for a 25% increase in the price of bulk tobacco in less than 60 days?

I believe you may be correct, conlejm ... The 25% increase does seem to be associated specifically with McClelland bulk tobacco. I consulted some bulk pricing for a few Lane Limited and Peter Stokkebye blends that I purchased from P&C during April, and there have been no price increases for those blends since I placed my order in April.
So, yes, the 25% price increase appears to be specifically associated with McClelland bulk tobacco from P&C.
Interestingly, less than 15-minutes after releasing my original post for this thread, I received a PM from one of P&C's online competitors (who is also a sponsor of PipesMagazine.com) which included the following text: "There have not been any price increases from McClelland." So, at least one of P&C's competitors is claiming that McClelland has not raised their prices on bulk tobacco during the past two months. I am confident that P&C must have a very good reason for implementing the price increase; and perhaps someone from P&C will comment on this thread.
Bottom line: I am not trying to "stir the pot" on this issue. However, I am using this forum to express my surprise and disappointment that my favorite McClelland bulk blends have incurred a 25% price increase in less than two months. That is a hard pill to swallow during these times of "cellar building" by those of us who are very concerned about the future of pipe tobacco availability and pricing in the U.S.
