A bit of an odd one.
Don't shout if it's a stupid question please 
Just doing my shopping online and I normally buy Tesco chickpeas in a tin at 55p. The east end ones are 40p a tin, but they are in salt water as opposed to the Tesco ones in plain water.
If I buy the cheaper ones and wash before use, they won't be any saltier will they? Does salt get absorbed in chickpeas? With the amount we get through (veggie household), it could be a good saving if it's not going to increase the amount of salt in our diet
