Discount codes that don't exclude holley parts?

Want to swap out my dual pumps for a single holley 12-347.
Paying retail for one is tough for me emotionally. Not sure i've ever payed full price for anything auto modifying related.
Any sites that i can find codes for exclude holley.
Could get it a little cheaper on ebay, but i'd rather have this particular item from a more reputable place.
Any of you guys have a way to get some type of discount other than free shipping?

I figured as much with the price fixing.

As for the pump, i haven't heard of the need for the surge tank. A friend of mine uses them in builds all the time.

Currently i run a fox style return system with a fuel pick/hanger with no pump on it. 2 external inline walbro gss340 (can't remember the exact model) high pressure pumps. It's excessively complex and has been bugging me for years. I did it before powerful in tank pumps were around.
It's worked well for me, but they are really loud outside the tank, like race car fuel pump loud.
My guess is if i was going to have an issue, this setup would have caused the same thing.

Not going to reinvent the wheel on this project. Would like to keep it simple, remove the twin external pumps, reroute the lines and filter and move on.
My car is a bit of a hybrid.
03 cobra computer and engine, but the rest outside the engine bay is all foxbody. I can't simply up the voltage to the pumps or turn multiples on.
The cobra tank $400, i can only image what a billet hat and 2 pumps costs and the rest of the supporting parts.
I doubt i will add any more power. Right now i'm into making into a nice reliable cruiser to drive around with the kids (they are little and will be in car seats in the back), hence the reason i don't like how loud these pumps are.
Not sure i've ever heard an in tank pump that's loud.
Going to switch the mufflers to super turbos.
Already finished the suspension the way i want it.
Not going to road race it, drag race it or probably even go wide open past the speed limit.

I'll consult my guys about the baffle thing, they have been doing foxbodys since 86, if they say i'm good i tend to listen.
I really wanted the aeromotive in tank pump, but they felt it would be too close to the limit.

So because i wasn't understanding how the hellcat pump could be any different than a stock style in a fox tank, i made a phone call. These guys have done this pretty much forever. They didn't get it either.
I know people call what's in a fox tank a baffle, but in reality it's a tub. A tub i've seen because it had broken off in my first tank, so when i went around turns low on gas the car would start to stall.

It's a return style system, so even if the pump is moving too much volume it's dumping the excess back into the tub. And my guess is that my twin 340 pumps (which i think are just 255's) are just as powerful as the single 525 so if it were going to be an issue i would likely have the same issue currently, which i surely do not.

Could you elaborate more on the issue causes the problem?
