For those that run business websites selling goods, please, have your programmer put (out of stock) or (backorder) if you don't have it in stock BEFORE your customer goes through with the order and payment process.
Mann Lake is a great company and has great products, but I do have a bad taste from ordering several times from them and only to get half the order in with a "BO" on the invoice. No other explanation, just "BO". A month later, I've called them and they said it was on back order... Oh, that's where the BO comes from!
If your ordering equipment for someone this gets quite embarrassing for a month to go by waiting for them to build/ship.
If anyone out there wants to buy the Golden Gate Bridge, I'm taking orders, but its all on back order until I get it built.
My last order from Mann Lake, I called them to make sure it was in stock and I got it within a few days. Lesson learned.
