I also wanted one of the wide ironing boards. The problem was that the money that I had to spend on it was in my PayPal account. It takes 4-5 business days to transfer money to your bank account - didn't want to wait. So I thought that I would order it on-line from WalMart (on-line they accept PayPal now). They had the option of the free ship-to-store option. But my experiences with S-T-S were not good. The items were ALWAYS delivered on the last day of the delivery window. But I was going to do it because I didn't want to pay out the wazoo for shipping. But I checked and the economy shipping to my home address was - $3.95 more.
$3.95 versus waiting for the money to transfer from PayPal to my account and having to travel to the store, get to the right place in the store with the correct information and then lugging the thing home.
So I paid the $3.95 and had it shipped to my home. I was kind of bummed because the delivery window was the same as S-T-S. I looked at the other two options of shipping - $12.95 and $18.95, I think. Well it wasn't worth THAT much money to get it sooner.
Longer story somewhat sorter - it arrived at MY door that Friday after ordering it on Wednesday morning. Talk about doing the happy dance. Tat was actually faster shipping than anything that they offered at the higher rates.
So you might try just buying it on-line. And double check on the shipping. Sometimes it is worth the extra money and sometimes it is not.
BTW - I asked the department manager at my store - the wide replacement covers are a new permanent item in the stores. If your store sells the big board, they will sell the replacement tops that fit them. HTH
EDITED TO ADD - And I LOVE the new board.
