Walmart offers two sets of The First Years Stack and Count Cups for $3.62. (The price on-page shows as $1.81 per set, but you are required to purchase a minimum of two sets to get this price.) Choose in-store pickup to dodge the $5.99 shipping fee. That's tied with our May mention and about $4 less than you'd expect pay for two sets in other local stores. Each set includes eight nesting cups with numbers embossed on the bottom. They are dishwasher-safe.
