We are very low budget preppers, we've never bought in bulk, all been 500g lentils here, tin of custard there.
I've just done an inventory and DH and I are rather proud.
10kg each of pasta, rice, lentils. Plus broth mixes. Packet mixes. Beans. Fruit. Custard and rice puddings. Meat. Fish. Sauces. Tomatoes. Veg. Very simple toiletries (soap - wipes - sanpro - washing powder)
We run apps that pay us in Amazon vouchers. Averaging £15 a week. The plan was to use them to buy dry goods, but we're better prepared than we thought.
Would you buy dry basics? Treats? (we are very good at not touching the stores) Toiletries?
It's essentially free money, but as we're low budget I'm loathe to waste it. Voucher balance is currently £32.50.
