**NOTE: THE FACTORY IS NO LONGER GOING TO HONOR PRICES BASED ON THE DATE SOLD RATHER WILL ADJUST THE PRICE BASED ON THE DATE IT SHIPS.  THIS MEANS IF YOU SEE A BLOWER WEBPAGE FOR $2000 TODAY, BUT THE BLOWER SHIPS IN 12 WEEKS FROM NOW, YOU WILL HAVE TO AGREE TO THE NEW PRICE AND WILL HAVE TO PAY THE DIFFERENCE BEFORE THE ITEM SHIPS.  PLEASE NOTE THAT BLOWERS HAVE ABOUT A 1% INFLATIONARY RATE PER WEEK.  THIS MEANS A $2000 BLOWER TODAY WILL COST $2020 NEXT WEEK AND $2040 IN 2 WEEKS AND SO ON. PROBLEM:  SOME ORDERS HAVE TAKE WELL OVER 9 MONTHS TO FILL AND THIS EQUATES TO 40% INFLATION RATE.  THIS MEANS THE FACTORIES COST HAS RISEN SO HIGH TO CONTINUE TO OFFER THE BLOWER AT THE PRICE ON THE PURCHASE DATE MAKE THEM UPSIDE DOWN IN THE TRANSACTION AND LOSING MONEY.  THEY NOW FILL IT IS BETTER TO CANCEL AND REFUND, OR COLLECT THE DIFFERENCE.IN THE PAST BLOWERS WERE ALWAYS IN STOCK AND NOW ORDERS ARE TAKING MONTHS TO FILL.  EACH TIME A ESTIMATED SHIP DATE IS PROVIDED, THE DATE COMES AND GOES AND GETS PUSHED BACK AGAIN AND AGAIN. 
POSSIBLE SOLUTION:  Check current stock level for this blower.  PLEASE CHECK AND SEE IF YOU CAN USE A DIFFERENT BRAND BLOWER OF THE SAME SIZE.  EXAMPLE A Roots 45 URAI IS SIMILAR TO A DENVER 4MR-RHC OR A TUTHILL 4005.  YOU CAN CALL OUR OFFICE AND SEE IF WE HAVE THE ACTUALLY BLOWER YOU WANT IN STOCK,  OR A CROSS OVER BLOWER IN STOCK.
QUESTION:  If I purchase a cross over blower and it does not fit, will Steambrite or the factory waive the 25% restocking fee?
ANSWER: No.  To purchase a similar performing blower is your decision as it states on every webpage, “All other warranties, express or implied, including but not limited to, the implied warranties of merchantability and fitness for a particular purpose, are hereby disclaimed”
THANKS FOR YOUR UNDERSTANDING.
