Buying in Bulk

There are a few things I have learnt that it's OK to buy in bulk, especially when they're on offer. Your main dilemma may be where to store them.
Each time I see the following on offer, I always pick one or two up.

• Bin Bags
• Washing up liquid
• Washing powder
• Fabric softener
• Loo roll
• Noodles
• Toothpaste
• Hand soap
• Shower gel

Morrisons have had a long running offer of their own brand shower gel and liquid hand soap on offer for 4 for £3 for ages now. I have a nice little stash in the bathroooms and that way I am guaranteed a shower without realising someone else has used the last of the shower gel and I am left with nothing.
