When to stock up on pet supplies (and when to wait)

Pet supplies are close to perfect stock-up goods: your pet eats the same food and uses the same litter every month, so a genuine sale is money saved on a purchase you were going to make anyway. The catch is telling a genuine sale from a price that was raised last month and then discounted. That is exactly what a price history is for.

Read the history, not the badge

A percent-off badge compares today's price with a list price almost nobody pays. A history compares today's price with what the product actually sold for over the last 90 days. If today is at or near the bottom of that range, it is a stock-up price. If it sits mid-range under a big sale badge, it is a normal price wearing a costume.

How the verdict on this site works

Once a product has 30 days of tracked history, its page compares today's cheapest tracked price with its own last 90 days and labels it a stock-up price, a normal price, or a wait price. Products with less history say so instead of guessing. The price drops page lists the biggest falls on the latest check across everything tracked.

What is safe to stockpile

Litter keeps indefinitely in a dry spot. Dry food keeps for months unopened, but check the best-by date on delivery and store it sealed and cool; buy only what your pet will finish well before that date. Wet food cans keep a long time and are the easiest deep stock-up. Flea and tick products carry expiry dates too, so stock one cycle ahead, not a year. Set a price alert on the products you buy most and the site will email you when one reaches your price, which beats checking sale pages by hand.

The discipline part

Stocking up only saves money if the stock gets used. Two rules keep it honest: never stock a product your pet has not already accepted, and cap the stockpile at what fits the shelf-life maths above. A bargain your cat refuses is just expensive clutter.
