You can ask Wilkinson's to send them from another store if your local one hasn't any in stock. I've done this many times if I find my store is temporarily out of something.
Just go to the help desk and ask them to 'IBT the goods' to your store. I'm not sure what IBT stands for but they look on the computer, find all the stores that have the product in stock, then request a chosen store to send it to your store. It takes about 4 days to arrive and they call you when it's in. You do have to pay up front though before the IBT is placed.
