We do the same thing.
There is a Lowe’s that marks plants down all the time.
The lilies that I posted were $1 each last year. We bought a bunch, red, yellow, orange.
Also, I bought flats of marigolds for $2.50 this year.
They just needed to be deadheaded.
They are healthy and beautiful.
I always shop the clearance areas at stores.
I used to have lots of beautiful lilies, then three years ago a menace came into my garden, a beetle that looks like it's painted with red lacquer, and it eats all of my lilies.
