Great Crates!

All this, for a little bit of supplies and rep? Are they insane? The amount of materials you need for even 1 crate is bonkers, let alone 6. The rewards need to be at least 20x higher for what they're asking.

the NPC you need to talk to is named Vashoinir, a boomkin, and they are located at `/way 52.51, 62.47`, standing next to [npc=211240].

They have a number of different boxes you'll need to contribute raw crafting materials to in order to "complete" a [item=210041].
A list of all of them can be found here: https://www.wowhead.com/ptr-2/spells/professions/name:shipment?filter=21;2;100200

It should be noted that you'll need 6 of these total (1 for the initial quest, which then instantly turns into "give me 5 more"). So if you go to the auction house, load up on enough materials to make 6 of these total (yes, you can turn in the same Shipment of Goods multiple times, so find the cheapest)

Both of the quests [npc=211240] offer (Great Crates! and Crate of the Art) require you to get [item=210041] from [npc=211236] a boomkin next to [npc=211240].

Great Crates! requires 1 crate while Crate of the Art requires 5 crates.

To get [item=210041] you need to offer tradeskill materials to [npc=211236] with any of the following transactions:

Cloth Shipment requires: 125xTattered Wildercloth, 25xWildercloth, 15xChromatic Dust and 3xVibrant Shard

Food Shipment requires: 15xRibbed Mollusk Meat, 15xBasilisk Eggs, 15xBruffalon Flank, 15xMighty Mammoth Ribs, 15xBurly Bear Haunch and then you'll need 50xDragon Isle Fish (this includes Cerulean Spinefish, Aileron Seamoth, Thousandbite Piranha, Temporal Dragonhead or Scalebelly Mackerel. You only need 50 of one kind of fish per turn in)

Islefin Dorado Shipment requires: 5xIslefin Dorado, 15xPebbled Rock Salts and 15xAssorted Exotic Spices

Diamond Shipment requires: 5xIllimited Diamond of the same quality (5x Tier 1, 5x Tier 2 or 5x Tier 3)

Uncommon Herbs Shipment requires: 1xAwakened Frost, 1xAwakened Air and then you'll need 25xUncommon Dragon Isle herbs of the same quality. The herbs available are: Bubble Poppy, Saxifrage or Writhebark. To say again you need 25 of the same quality and of the mentioned herbs to contribute to this turn-in.

Serevite Shipment requires: 1xAwakened Fire, 1xAwakened Earth and 100x[item=190396] (the Serevite can be any quality but it must be a stack of 100 of the same quality for the turn-in)

You can do one form of shipment 6 times or mix it up by getting a few here and there or even 1 of each. There are no restrictions on which shipments you can use.

EDIT: It looks like the shipments can change week by a week. I'll try to update add them as they're revealed (if I remember)

Rare Gem Shipment requires: 25xAny of the 5 Dragonflight Rare Gems of the same quality ([item=192857], [item=192853], [item=192863], [item=192860] or [item=192867])
