Hi, at work today I found my colleagues buying some of these but because I was on the afternoon shift, they had sold out of the bars (although some of the 'One by One' boxes were left!!! Apparently they had put them on sale at the front of the store and within hours all the bars had gone!
What is on offer is 200g regular bars of Toblerone (in cream coloured boxes) at 29p. The 'One by One' boxes contain individually wrapped triangles in an assortment of all the flavours (eg. white, dark, milk chocolate etc) and are 99p for 200g.
Obviously the bars are the bigger bargain, however the boxes are also great value considering how they are normally over £3 in some other shops! These would probably be a good substitute for things like Cadbury's Miniature Heroes etc.
I thought though that it might be worth sharing this with you guys because it may just be that other stores have some left (or as is often the case, they may not correctly be priced on the shelf so are worth hunting out as they go through the till at this price!) Otherwise, perhaps the staff at your local store may not have been arsed to put them out yet/may be waiting to put them out tomorrow since Tuesday is usually the day for new deals at Superdrug!
I think there will be many 'One by One' boxes available as this appears to be one of their weekly specials - my store usually has different items available at 99p each week for 7 days only and these items are well stocked!
