I thought I understood that IKEA Houston was more expensive for certain items because it is a franchise store.

I have the kitchen catalog and general catalog from the IKEA Houston store. The prices in these catalogs matched the prices I saw in the store on items and are higher on many items than the prices on
http://www.ikea.com
I just found the price list here on Ikea Fans under the Door Styles page and compared it to my Ikea Houston Kitchen catalog and it is exactly the same. I then compared the price list on Ikea Fans to the prices listed on
http://www.ikea.com and the prices on
http://www.ikea.com are cheaper. I am confused.
Which price list is correct for which store?
Is the price list on the Door Styles page a price list for Ikea Houston?
Anyone that has purchased cabinets at Ikea Houston, did the prices match the Ikea Houston catalogs or did they match the ww.ikea.com site prices because they are different?
Anyone who has purchased cabinets from other Ikea stores(non-franchise), did the prices match the price list on the door styles page or did they match the ones on
http://www.ikea.com?
I am trying to figure out whether it will be worth it for us to drive to Frisco instead of Houston to purchase our cabinets of if we are just going to have to pay more because it is more convenient to go to Houston. :?
I used the tall pantry cabinet HPO1588 as a comparison and it seemed to be about $32 more per cabinet on this tall cabinet regardless of door style. The 4 drawer cabinet B4D36 seemed to be about $6 more.
Any thoughts?
Thanks
