RE: Jr Servos
It's pretty difficult to find discounted JR servos. If you are OK with buying used servos, you can find some pretty good deals on JR servos in the classifieds here on RCU.
Make sure that cheap servos are really what you want and need.
If you use a light-duty servo for a heavy-duty purpose, it can turn into the most expensive servo you ever saw, after you've trashed your plane because of a servo gear strips out. (Don't ask me how I know that.....)
I start to look at higher duty level servos when my application is either for 3D or for 60-sized planes and up. I only use standard servos for light-duty uses in something like a 40 sized trainer, or for my throttle.
Despite what some say about them, I have had very good luck using JR DS-821 servos, and they can sometimes be found at a great price. (For what they are....) They have a better than standard torque rating, and they are digital. Digital servos center better than analog servos, and have better resolution. Personally, I don't use these when the application gets over 90 sized planes, although JR says they will work on up to 120 sized planes.
If you ever lose a plane that you REALLY liked, just because the servo gave out, you tend to be a little nervous the next time you are deciding which servo is "good enough".
If you are flying helicopters, they are even more demanding on servos.

RE: Jr Servos
Here is an ad for some JR standard servos at a pretty decent price, if you want to buy five of them. (I do NOT know the seller....)
