PVAS will try a group buy for Frozen Foods through Brine Shrimp Direct. Check out their webite offerings brineshrimpdirect.com but not their pricing. Special pricing on the cube packs for a club group buy, especially if we order 140 cube packs which will fill one box. Suggested cost for frozen bloodworm cube packs , shipping included with dry ice packaging, would be approx. $3.77/pack (see photo image online). Let's just say about $4 for now, exact cost can be worked out later. If you are ordering, you must need multiple packs, right? Ordering through their website, 21 bloodworm cube packs comes to $6.46 each with shipping!!! What a great savings to order in bulk. Other types of cube packs are also available, many are far less than the bloodworms. Pricing offered BEFORE SHIPPING COSTS ADDED: Mysis cubes, 1.28 Arctic Copepods 3.15 Ay Caribe, 3.45 Brine cubes, 1.08 Bloodworm cubes, 2.25 Copepod cubes, 1.28 K. Pacifica cubes, 1.08 Rotifer cubes, 1.28 Flat packs are available also. If we don't come up with enough orders to get these great prices, PVAS will not be placing an order at all. Final date for ordering will be THURSDAY 8/25 . I can do my best to answer questions, but my best answer will be order plenty and you won't find much better pricing and you still have to drive to your favorite pet store to get some. oldglory2001@gmail.com
