Simply don't buy from them. The large chains are entirely profit driven. If the aquatics center becomes a loss leader, they will revamp it. It's happened in the past, but Walmart to cite a specific hired an independent 3rd party to try to salvage the section. Every "I saved a Walmart (insert any chain store) betta" thread equals a sale and enables them. I personally doubt that the loss of their sales will drive up prices, but I can see some of the reasoning behind that idea with drygoods. The difference is that the drygoods they sell are not the same ones that non-tinkerers seek out and purchase. So what? Tetra and Top Fin take a hit... that won't affect the brick and mortar or online merchants in any significant way. Livestock is similar.... the less chain store fish sold, the more that the responsible outlets can demand quality over quantity. Price may be impacted on a small scale, but in the end the mass merchant won't be the one driving demand. It will be consumer choice and real demand. Those $2.88 fish wholesale for around $1.25 for most and $.40 in huge supply. If the profit margin differential is narrowed, then the true hobbyist and the true LFS
wins. I ramble so I'll quit... I've spent many hours of research, thought, and debate involving this issue so I do take it a bit personally.
