(CNN) — Getting toilet paper, cleaning supplies and cold remedies delivered to your door just got easier.
On Tuesday, Walgreens announced a formal partnership with on-demand delivery startup Postmates.
Using Postmates’ app, customers can shop from the drugstore’s catalog of items — or order a prescription — for a $4.99 flat fee. The delivery service, which launches Tuesday, will be available at 600 Walgreens and Duane Reade locations in 30 markets. Postmates is guaranteeing delivery within the hour, but says, on average, it’ll take about 30 minutes.
Postmates — which raised $80 million in funding in June — already counts companies like counts Starbucks () and Chipotle ( ) as partners.
And last week, Holger Luedorf, Postmates’ SVP of business, told CNNMoney that it’s working withEtsy () on a new type of service called ASAP.
ASAP will deliver Etsy goods directly from artists to customers and will start out in New York City before expanding elsewhere. This expands on Postmates’ traditional delivery service — coordinating logistics between the buyer and the seller.
Luedorf said the Etsy and Walgreens () deals are just the beginning of Postmates’ expansion into the retail goods market.
There is no shortage of competitors in the space. On Tuesday, grocery delivery startup Instacart said it was formally partnering with Target ( ). And earlier this year, Amazon ( , Tech30)announced a new Prime Now delivery service.
Postmates, however, isn’t showing any sign of slowing down.
“Be prepared for a number of partnership announcements in the coming months,” said Luedorf.
