Is there a walmart super center in oahu hawaii or are there just regular walmarts?

There are five Walmarts on Oahu, none of them are supercenters. The locations are:

There are locations on other islands and a new store is coming to Kapolei in spring 2012.

The Pearl City location opened in early 2006 and was remodeled in early 2012. Walmart still lists this location as a traditional store, but a number of customer-review sites refer to it as a supercenter.
