Calculate the price for the meal you actually ate
If a kit cost $24 including delivery and fed two people once, the price was $12 per person. If that same kit also supplied a full lunch someone ate the next day, the three portions averaged $8 each. An unused portion should not bring down the cost per portion eaten. Record additional ingredients bought for the recipe, especially if you would not normally keep them at home.
Measure the work the kit removed
Compare it with your real alternative for that evening. On a packed Thursday, that might be takeaway rather than a low-cost meal cooked from scratch. If the kit regularly arrives on a night you cannot cook, change the delivery day before trying a larger plan.
Time the household jobs the kit was meant to replace. Did you avoid planning a menu, making an extra trip, or measuring unfamiliar ingredients? Did one person still have to spend time chasing a missed delivery? Record the work on the night you used the kit, not an ideal worknight.
Choose the next order deliberately
If you would order the meal again, name the reason and the right occasion. A kit that works on relaxed Tuesdays may disappoint on rushed Thursdays. Check the next order date, menu, and actual price before repeating it; an introductory price or a particularly convenient delivery week may not describe future orders.
