You can get a pair of Dunlop D205 or D220's for ~$200 online (shipping included). Maybe less if you shop around more than I just did. I just went to
one place I know usually has some of the lowest prices. The D220 is Dunlop's latest sport-touring tire, while the D205 is their "older" S-T model. (The D220's were ~$4/pair more than the D205's.) Many folks prefer the 205's over the 220's. I don't know though, I've never used either one.
So, if you can get tires mounted and balanced for less than $60, you could save some dosh. Where I am, it costs me $40 to get a pair of "carry-in" tires mounted and balanced. (I could save another $10, but have to go another 50 miles to the other side of Metro Seattle - and that's not worth it to me.) For a $20 savings, I don't think I'd bother. It's nice to support your local brick & mortar shops when they can be fairly competitive. If you don't they'll disappear and then there won't be anyone to mount & balance your baby's new shoes.
You can try to see if you can barter their price down with what you can find with your on-line shopping skilz. Sometimes it works.
