Discount deals and Brexit uncertainty are encouraging people to bulk-buy, but be savvy if you want to avoid waste later on.

Nine in 10 shoppers claim to be committed bulk-buyers, new research has found. And with 89% of people saying they buy in bulk, it's not just a good deal that's enticing consumers to stock up on items they won't immediately use.

The top 10 most popular items for people to bulk-buy are toilet paper, washing powder, toothpaste, shampoo and conditioner, baked beans, frozen food, soap, pasta, rice and meat, the survey found.

But for many, their bulk-buys can often end up going to waste, with 44% of consumers admitting they eventually throw away goods they'd previously stocked up on.

Are you keen to stock up? Here are's top tips for being a clever bulk-buyer...

1. Do your maths

Special offer labels can be enticing, but work out the cost per item or per gram to see how much you could save by buying multiple items rather than just one or two - it may not be as much as you think or anything at all. Use the calculator on your mobile phone if you need to.

2. Set a bulk-buying budget - just as you might for your regular shopping

Weekly budgets are essential for ensuring you don't feel the pinch. If you decide to bulk-buy products, make sure you put away a little money each week, so you spread the cost evenly across the year. Doing a big bulk-buy shop can leave you short in the months to follow if you haven't planned for it.

3. Make a list of the items you regularly cook or use

These will be the items that are most important to bulk-buy. This will stop you being distracted by deals for items you don't need.

4. Bulk-buy expensive items

Make a list of the expensive items you need such as washing powder and razors and make a point of looking for bulk-buy deals. As you don't need to buy them every week, you can wait for a good deal before stocking up.

5. Make more use of the freezer and canned foods

Don't bulk-buy perishable goods unless you're able to use them immediately - or see if some can be frozen.

6. Check how much storage space you have before going shopping

A lack of space could result in having to throw items away to make room for new purchases.

7. Shop big

Buy from wholesalers and discount stores, who may have great deals when bulk-buying.

8. Join forces

Pairing up with friends, family or colleagues means you can split the purchase and still end up with the same deal but without a large amount of stock to store at home.

9. Make note

Keep a note of sell-by-dates on items and make sure you are using products before buying more.

10. Only use the amounts you really need

Having an overflowing amount of items can encourage people to use bigger amounts in a more wasteful way, knowing they have a back-up.
