Preppers are the type who like to be prepared for anything for the long term. They don’t just look at the short term goal of surviving on their own for a couple of days while the government and emergency services mobilize to send help. Anybody who is doing that may be waiting for a long while. When you are thinking long term, you will need a lot of supplies, not a single box of matches or a single bottle of water purification tablets. You need a lot, which is why buying in bulk makes so much sense.
Buying in bulk is typically more cost effective. You can buy prepping supplies by the case load and get a significant discount. Things like hand warmers, emergency blankets and water purification supplies are just some of the things you will need a lot of. Buying individually can get expensive in the long run. You will pay anywhere from one to three dollars for a single blanket. However, when you buy in bulk, you can often get that price to under a dollar.
While many preppers will say they can’t afford to spend $50 on a case of hand warmers, when you break down the price for each pack, you are going to spend nearly twice as much if you buy a pack here and there. It makes good sense to save up and make those bulk purchases. It will ultimately save you money and you will have more supplies to put on your shelves. You can always use the extra you have to trade for other things you do need.
This isn’t to say you shouldn’t take advantage of clearance prices and sales on the individual packs. Always be on the lookout and do your best to catch sales. Adding a little at a time to your emergency storage is okay, but if you find an opportunity to buy in bulk—go for it!
