The sale started today and goes for a little more than a week.
Livestock 40% off However, inverts are still ridiculously overpriced, even with the 40% off.
Food, including frozen 50% off $12.50 for Rod's
I used to shop at Aquarium Adventure as my primary LFS when I was first starting since it is like a 10 minute drive from my parents. I discovered when they have their sales, they artificially increase the prices of their livestock so after the 40% off, it ends up being not a whole lot cheaper than their normal prices.
I remember seeing Discus at $60, or $51 for fish club members. On the 40% off sales, the "original" price would become $75, so the sale price is $45. Sure it was cheaper, but it wasn't as amazing as they made it out to be.
Every now and then though you would find decent deals.
