I too have ordered some today. From one site is was free postage and would come in normal post, from another site it came with the instruction "Please note this is a fridge line and we will send via Special Delivery", obviously at additional cost. I ordered from the 2nd site and have paid the £5.95 delivery fee. I know last time I ordered it it came in normal post from the 1st site, but like you I have never used it so have no idea if the length of time it's not refrigerated makes a difference. I also stored it in the fridge.
Be interesting to see what others say.
