@Dennieee Years ago I used to order plants from QVC (haven't in about 10-12 years.)
More than half did well. Some didn't, partially, due to the climate in CT, and care I wasn't able to consistently do (planted many down at my mom's, and due to mobility issues needed help with maintenance.)
Day lillies & irises did very well at mom's. Low maintenance plants, for her, were best. The irises didn't bloom the first year, but after that came back year after year & were beautiful. I planted some at my bf's also that did well. But my local nursery has a beautiful, varied selection of Irises; if I ever do them again, I'd go there.
I did a Cottage Farms blueberry plant, I had zero luck with. Started it at my place for two seasons, in a pot (I'm in a 2nd floor condo, only do pots.) In the pot never had fruit.
I replanted it at mom's, in a very sunny spot & it never did well there either. With some mobility issues, she couldn't water easily, and I'd only get to water it once or twice a week there. What one or two berries came...never ripened and got eaten by rabbits. Never did fruit again from QVC, or from local stores either, lately...just focused on flowers.
I had a set of small rose plants from Q. Had one on my deck one season and it bloomed pretty. Then replanted some at mom's, some at bf's. Mom's never grew or lasted. Bf's turned into a very large, beautiful rose bush, that bloomed a few times a year, until a disease that was going around CT got it a few yrs ago. 
Overall, I mostly had luck with QVC items, but finally decided to stick with my local garden stores; we have many great ones, I love to visit, including an organic one.
Pricing is about the same either local/QVC, but there's sales, membership deals I get at local stores, and a large, varied selection. I go to ma/pa shops, but @Dennieee I've also gotten things at Home Depot, and like Lowe's, as you said...pricing can be good, items are fine there, nothing unusual, but the basics.
I still enjoy watching QVC's garden shows, particularly in Feb/March when spring is hardly in bloom here in CT for another good month or two. I did buy a cute Bunny planter from Carolyn's line this season. I love it & already have a plant in it. 🪴 🌷🪻 🌱 🌞
