A Good Deal on Fruit Trees

So Lowe's is having a sale on a lot of their trees and I was able to get two more fruit trees. A Santa Rosa semi-dwarf plum and a Red Delicious semi-dwarf apple. And they were 75% off, so I only paid $5 for them.

Unfortunately I then realized that all these trees need pollinators. Meaning you need more than one variety for each one to pollinate with. I already have the other apple. But I need a partner for the peach and the plum. But this Lowe's doesn't have anything left except a couple apples. I'll have to make a trip to another Lowe's not far away to see what they have available. Wish me luck.
