Walmart
The new face of the previously-titled Delivery Unlimited service offered by Walmart, this feature offers exactly what it's named for: unlimited free delivery. A wide array of product categories are covered under the umbrella of unlimited free delivery, "from tech and toys to household essentials and groceries," all available as soon as the same day you order, or with one-hour pickup. However, eligibility is variable; you'll have to enter your address to find out if you even qualify for service.
Just like its predecessor, Delivery Unlimited, Walmart+'s unlimited free delivery service requires no minimum purchase value, nor does it throttle your delivery frequency. The feature allows members to order as often as they please, without paying a delivery fee outside of the yearly or monthly flat membership rate. Previous subscribers of the Delivery Unlimited service will automatically be enrolled in Walmart+.
