When you think of a dollar store, you may not necessarily think “delivery,” which can be kind of a splurge. But dollar store delivery is becoming more of a thing. The discount retailer Dollar Tree recently announced its customers can now get their purchases delivered through DoorDash. And shoppers can already get stuff delivered from the two other big dollar store chains: Family Dollar and Dollar General.These discount retailers are meant to offer value. But when customers tack delivery fees on top of that, are they still getting a deal?To find out, I opened up the DoorDash app and did some shopping at the Dollar Tree a couple miles down the street from my house in Baltimore, Maryland.I bought sippy cups — $1.25 for two is pretty good — some snacks, and toilet paper. The total bill was $5.25, definitely a deal. Fees added another $6.48. Tack on the tip, and I ended up paying more to have the stuff delivered than for the actual stuff.It arrived in about 20 minutes. David Smith, my Dasher, said a lot of his deliveries these days are from dollar stores.“It's convenient,” he said. “You might be at work … you can’t leave the house, but you need these items. If I can pay DoorDash six, seven dollars to bring me everything that I need … Why not?”Smith doesn’t get stuff delivered himself. But he said his wife does it all the time.“I'm a Dasher, laying watching TV beside her, ‘Just tell me to go get it, I’ll go get it!’” he said. ”But she says, ‘I don’t want to bother you, you need your rest.’”Dollar store customers need delivery, said Bryan Eshelman with Alix Partners. He’s done some consulting for Dollar Tree in the past. “They have a customer that in the urban and suburban environments … are less likely to have access to a car, and so having this kind of delivery service is a good service for them,” he said.Eshelman also said in-store purchases may be in cash and are kind of anonymous.“[Delivery] allows these retailers to have a better visibility to what their shoppers are actually shopping for,” he said.Being on these delivery apps gives dollar stores a chance to be discovered by new customers, said Natalie Kotlyar, who follows retail trends for the advisory firm BDO.“Historically, they could only reach the consumer when the consumer comes into the store. By offering a delivery service, this creates a whole new revenue stream for them,” she said.Kotlyar said there’s something kind of democratizing about being able to get discount goods delivered. Basically, whether people have less money or more money, sometimes convenience is something they’re willing to pay for.
