In The Elder Scrolls V: Skyrim for the PC, PS3, and Xbox 360, you can invest in stores to increase their gold limit permanently. This can be very helpful, especially at stores you frequent the most.
First, you’ll need to get your Speech skill to level 70. Check out my other guide for tips on how to level Speech quickly.
Once you have Speech to level 70, you just need to purchase the Investor perk in the Speech skill tree.
Once you have the Investor perk, you will see a new dialogue option when speaking to shop owners to help them out and give them 500 gold. This will permanently increase their gold limit, and you will gain some favor with them as well.
Investing into shops also counts as helping people out when trying to become a Thane of a region.
