Portatech.com waste of time and money

I am advising that people think twice before using Portatech.com for purchases of gear. They have notoriously low prices and take your cash, send confirmation, tell you that the item has shipped and then inform you that they are sold out. I purchased in excess of $1800 worth through them and all they did was slow me down and cost me money. Their initial response was certainly uncaring and cold at best. It just seems to me that they skate a tad to close to bait and switch. I have a few email exchanges (business-like) where they begin to defend themselves but they are far from a good deal, a safe bet or a good business. If you want to have your money tied up for days, told that they have stuff and that it has "been shipped" only to find that they never had the item...then use them. My experience was very bad to say the least.
