Time to reopen the Little Shop at the end of the garden!

Popped into the Little Shop, just looking, you understand.
There was a big sign in the doorway - "Chewsday Special! Lucky Dip for every customer".
I picked up the usual mix of green leaves and went to checkout. "Do you want to try your hand at the Lucky Dip?" asked the shopkeeper. I didn't like to say it was the only reason I'd called - so I didn't!
"There you are, young lady" he said, patting his assistance dog, "Have a furtle in that tub and see what you can find."
It was one of those 30ltr tubs, that he grows his plants in, full of damp soil. Rather gingerly, I had a little rummage around the roots and uncovered a bright, shiny new potato. So exciting!! There was no stopping me now. I furtled and rootled, rummaged and grubbed until I'd found enough potatoes for dinner tonight.
I thanked the shopkeeper effusively for such a special, Special Offer. Come back tomorrow, little customer, and there'll be another special offer for my loyal customers.
I probably won't sleep tonight, wondering what it might be.
