Quoting from the FAQ, updated May 15, 2012, available at the RFL display:

Where can I get one?
The Meeroo Store is located in Second Life on Roo: http://slurl.com/secondlife/Roo/85/85/21

It should be made clear that one cannot purchase Meeroos at this location.

OR

Can be purchased from this exclusive store in the Second Life Marketplace:
https://marketplace.secondlife.com/stores/89733

It should also be made clear that one cannot purchase Meeroos at this location either.

Please remember you must have access to Second Life and have an active avatar in order to play Meeroos. These are Free accounts and can you can join Second Life here:

How much are they?
We typically have a multiple options to give you as much choice and flexibility as possible... However, after the initial release of an expansion, we will sometimes remove starter packaged from our markets in order to encourage user to user trades and exchanges. When starter packs are available, they can be found in these package sizes:

Meeroo Packs
Meeroo Family Pack: 6 Nests, 2 stump, 4 Weeks of food for 6 Meeroos, HUD = L$ 5199
Meeroo Medium Pack: 4 Nests, 1 Stump, 1 week of food for 4 Meeroos, HUD = $L 2799
Meeroos Pair Pack: 2 Nests, 1 Stump, 1 Week of food for 2 Meeroos, HUD = $L 1599
Me and My Meeroo Pack: 1 Nest, 1 Stump, 1 Week of Food for 1 Meeroo, 1 HUD = $L 999

It should be made more clear that Meeroo starter packs are not available for sale.

Since Meeroos are not available for sale from Malevay, potential customers are left with their single, most important, question unanswered: how to I obtain one?
