Due to the overwhelming nature of these Dollar Per Gallon sale events that Petco has been putting together, I have decided that it would be smart to condense all of the possible dates into one section for a future reference on when they may appear on. Although many other retailers have adopted such a sale (they may call it something else), this is when nationwide almost all Petco stores (excluding Alaska and Hawaii) have this sale going on. Normally during the middle of this sale, they will have an aquatic event, where many of their fish, plant, and decorations will also go on a massive discount for days.
Currently, the only tank sizes that are being sold during this event for the sales price include the 10 gallons, 20 gallons, 29 gallons, while the larger tanks ranging from 40 gallons breeder, 55 gallons, 75 gallons and 90 gallons are 50% during the sale. In the past, these sales were supplied by Tetra, however, due to customer complaints, these sales moved over back to Aqueon (who was the original supplier when Petco had this sale event idea). These sales do not include any kits, and therefore the tanks that are the sales price will not include anything extra besides just the tank. Sadly due to location-wise, Hawaii and Alaska are excluded from these sales due to the shipping cost required to make it to these states.
In more recent years it appears that other major retailers including Petsmart are also incorporating this dollar per gallon sale event into their market as well. This may or may not be due to the fact of many of these retailers having a price match guarantee, in which they will match the price of an item if it is the same brand and same size (and due to how popular Aqueon brand tanks are, they are forced to follow their policies). Check with your local retailer to see if they have such a guarantee since it is a great way to score one of these tanks if a Petco is not located near where you live.
To provide all of the dates (past, present, and future) we needed to have a way to distinguish them apart. Currently, any rumored dates will be in italics, valid and verified sale dates will be bold, and past dates will be included inside of the spoiler area below.
