Price check on battery packs

I am replacing a battery pack. Last time used these - Turnigy 5000mAh 5S 20C Lipo Pack

Today, Hobbyking shows these lower priced packs:
Turnigy 5000mAh 5S 20C Lipo Pack $46
ZIPPY Flightmax 5000mAh 5S1P 20C $45
ZIPPY Flightmax 5800mAh 5S1P 30C $45

Are these still fair/good deals or are others better value these days?

TIA don

There are no other brands of LiPoly that are worthwhile except the Multistar, but they do not offer 5S bricks.
Those are the reg. prices, but Hobbyking doesn't seem to be putting their LiPoly on sale these days. They are continuing the free shipping policy though.
I've used both the Turnigy and the Zippy Flightmax and I think my Turnigy's have lasted longer.

The price was good and I have ordered the Zippy 5800, to build a 11.6Ah pack that is pretty compact. Free delivery in 5 days, that was quick. Earlier this year I had ordered a bunch of Zippy 8000 to make 3 packs. Received all good in 2 weeks. After having shipping problems to Canada, I had left HobbyKing aside, but now they are back on my suppliers list. They are low in stock though.

Batteries are actually getting a bit more expensive now. The old supply and demand thing

For USA shipments, is HK still the go to store, what others offer good quality, pricing, and service for US delivery?

I would expect prices to be higher and stock to be more scarce in the summer months
