mog garden fame?

[Cyriack]

what can i do to raise mog garden fame?

There's no "Mog Garden Fame." The only way to improve your areas in your Mog Garden is to actually work on them. Once you've done enough in a section such as the coastal net or the groves (sometimes it takes a long while in some areas), you can buy a new KI from either Zenicca near the West Adoulin Mog House or the Skipper Moogle in the three starting nations. This will upgrade the area relating to the KI by one rank.

was referring to after u have completed mog garden, buying stuff from moogle wondering if it could be cheaper.

There's no "fame" for that no. Prices are set.
