plastic bottles for dry storage?

[I-K-E]

just a quick question how many people us old plastic bottles for storing dry food like rice, flour, oaks etc

the reason I'm asking is that at the moment I'm looking into the cheapest options as we very little spare cash but the OH doesn't drink tea or coffee and drinks cordial instead so as a result we have a constant supply of bottles that tend to go into the recycle bin.

One plan is to clean out, dry and use these instead of mylar for home storage maybe with some home made oxygen absorber from a thread that Tigs posted.

Some supplies will be in longer term storage the rest in a 1 year rotation ultimately

so was just wondering what experiences people had with a simular idea

thanks
