ETA Here is is
Thank you very much for your email. You are correct in that there are two versions on Mug Shot out in the market in the sachet form, the classic range and the new range that is available in the discount retailers.
...
Traditionally we sold the same product to all retailers. Whilst the main supermarkets sell the sachets at around or over the 70p mark the discount stores are wanting to sell on deal at 3 for £1 so 33p per unit. They have been selling at this promotional price for a while and we tried to maintain this for as long as possible. We could no longer maintain this promotion with the existing product range and so we were tasked with developing a range of products they could continue to offer at this fantastic price. This is how the new range was born.
We tried to change as many elements as possible to highlight this was a different product, the brand name colour the colour of the mug, the name of the flavours and the type of pasta used. Unfortunately without any means of communicating in the stores they are sold in it has caused a bit of confusion and we are sorry about this. On the Chicken flavour we are intending to change the name on the classic range to further highlight a difference between the two products. Unfortunately there wasn't much we could do with the flavour name when we launched the new range of product into the discounters.
With regard to the difference in the products, we have tweaked the recipes. The new nutrition values have dropped slightly, so lower fat and energy values compared to the similar flavour in the classic range. Due to the way Slimming World calculate the Syns they regard these now as not as filling due to the slight drop in levels and so have given two of the four Syn values. Chicken 1 Syn and Tomato 1 Syn. The other two have remained on par with the similar flavour in the Classic range Sweet and Sour is still 0 Syns and Cheese still 2.5 Syns.
I hope this goes someway to explain why we have done what we have done and apologies again for any confusion caused
