Many people are totally fine with buying cheap crap. As long as they know that going in, that's great. Walmart is indicating with their prices that they're offering lower quality merchandise, which many people find acceptable because the cost is lower. It's honest.

I think a lot of people overvalue what they think they need--basically YAGNI. There is a bit of once burnt, twice shy. I learned when first moving out to go to the dollar store to fill my apartment; bathroom trash can, shower curtain rings, kitchen cups/plates, toilet brush. Then upgrade what doesn't work (paper-thin shower curtains will billow with the steam and stick to you). It wasn't as wasteful as I had expected and I saved a lot of money compared to just buying everything from the average retail store.

Even Wal-Mart plays on this by stocking name brands here and there.

are there hundreds of millions of enterprise customers for your SAAS product?

Sometimes shooting for enterprise customers doesn't work. Some products need the little guy to survive, not global international enterprise companies.
