As far as prices go, seems like Walmart has them at $4.89 for 6 mini cups (12oz total or 340g) or a large single package of 15oz/425g for $4.98. An average avocado weighs 136 grams without the pit or skin according to the USDA. Let's say 1/5th of the total weight of avocado flesh you buy is spoiled in some way (too stringy, too hard, spoiled etc.) At $1.25 per avocado and 20% spoilage, the large single package of Wholly Guacamole and the avocado are nearly the same price. Various sources claim that the average US avocado price is around $2 but when I buy them myself I usually get them around $1; I suppose if you're paying more it's an even better value.
So, looks like a good value in addition to saving on spoilage. My only worry would be the plastic waste, but I can't seem to find what the containers are made out of and if those are recyclable.
