Okay, online they sell pumps at numerous different websites. But, the most popular pumps is the mityvac and they're selling them at a price range of 75 to 100 dollars! Well, I was at Harbor Freight (a discount hardware store) the other day when i noticed a mityvac on the shelf, along with a TON of other pumps I've seen online. The mityvac at Harbor Freight was only 25.00! and the cheaper ones were like 15! I then decided since I can get a good pump locally much cheaper and faster I'm gonna get heavy into pumping! Which is another point... you can pump and get HUGE without spending more than like 40 bucks.. go to wal-mart and get one of those tea jars and a mityvac and you're set!
