You can still buy bottled Coke if you look Frank,a quick Google on Sainsbury's and Morrisons and they have them on sale for £2.80 for four 250ml bottles or £2.50 if you buy the Zero version (no sugar) Nip in and buy yourself a fivers worth as a treat and you are right,they do taste better
There was some great chocolate back in the day and my favourite was a Icebreaker but nobody seems to remember it,rum flavoured Areo to and I'm pretty sure that they did a strawberry version as well,the most outrageous taste that they do now is probably mint,do you think that the chocolate recipe has changed over the years,was there any E numbers back in the 70's or stuff that they aren't allowed to use anymore,I bet that the chocolate tasted better if we could go back,Google's 70's sweets images and see what you can remember and I bet that some of them will take you back to your youth
