What to do if you sent off a money order with an amount lower than the total cost of a product. I went to a st? -

I went to the grocery store to get a money order for $174.00 which I thought was the total cost of this product i was buying. i realize later on it was an extra 10.00 for S H which I must have overlooked. So the total cost is $184.00. I already sent the money order off and I m a bit worried i will not receive the product. What should I do?

it is not a big deal, because just for $10, moreover, you overlooked it, and you were not intended to do it...
