Sorry you had to close shop. But my husband did guess right, that you're a former shop owner.
Similar stories, just different job descriptions. People can't buy cars/GM can't sell enough cars. GM can't sell enough cars/my husband's former business can't sell door repair to them. So now he sells stones. We don't sell enough stones/we can't afford full-priced diving equipment.
This sort of thing hits everyone from the top down. It's all a downhill roll when the economy takes a big dive (again, pardon the expression). We all have to do what we can to get by.
Best of luck.
My cynicism runs deep at times. I should not have come off so caustic.
Internet Vs Local Dive Shop is a widely contested and discussed topic here. Right up to the point when a diver needs an air fill. Then the discussion is over.
We use to get droves of "customers" that wanted to try on equipment or have us repair 20 year old equipment bought at a garge sale and then proceed to balk at the price or suggestions to obtain gear that was actually serviceable.
Those tanks you saw being filled were likely connected to a 10-$20,000 compressor. Fill cost? $5. The tanks you saw being sold? MAYBE a $10 mark up which likely included a free air fill and visual inspection.
Personal gear like mask fins and snorkel is really where the retailer does well.
Your husband was half right. I volunteered my time working as a divemaster and general tank monkey to keep our LDS running. To see it close down sucks none the less.
Everyone has suffered to some extent due to mishandlings of the economy. I hope your business does well.
