Short answer: make a list by project before the sales, work out how much resin you really need, and compare kits by cost per ounce, not by the discount badge. Deals vary by store and change quickly, so always check the current price yourself. Don't stock up on more resin than you can use within about 6–12 months, because hardener ages.

It can be, but deals vary by store and product. Compare the price per fluid ounce and buy only what you can use before the hardener ages.
Non-perishables like silicone molds, mixing cups, a scale, gloves, a heat gun, mica and a respirator keep well. Buy resin itself closer to when you'll use it.
Check the size (combined A+B), work out the cost per ounce, and compare with other sellers or the product's usual price.
