Vendor House
 

When I go to sell in my house I am only allowed to sell 5 items, one row. All the other houses have numerous rows of boxes to sell items in. How do I get mine to expand like theirs?

The only way to expand your shop is to buy a multi house from Cash Shop...

Multishops gives 5 extra spaces... (so 10 all up)

If you want a max of 20, I think there's something called a storage pack, that will expand the shop further up to 20 slots...

"sign of tycoon" sc item adds ten slots to vend, sc house adds 5 slots

yea i realized that happens to me also =\
i'm not gaining as much money i would like but its better than nothing =]

if you buy one of the mini homes with sparckcash you get 10 slots also.
