A quick question. Got my darkroom set up about a week ago. For printing I've been using some paper I got off ebay, Agfa MC RC. I also have a couple of other boxes of Ilford paper which I've picked up along the way. Some of these packets have been opened and one box I binned when I discovered it was fogged.
I'm going through an extreme learning stage, namely starting from scratch and am going through sheets of paper like there's no tomorrow. What effects could I be getting from using old/unknown history paper, e.g. contrast, responsiveness etc. and could this lead to unpredictable results that I will think are normal due to not using new paper stock?
I know the easy answer is just to buy some new paper but with the amount of paper being sold on ebay I'm sure there are a few people in this situation.
As an aside I've noticed that if you shop around then new paper can be bought for only a couple of pounds more than some of the stuff being sold preowned.

When you order those new chemicals from Nova they will do you a very good deal on a box of Ilford 10x8 MG R/C; about £20 I think
; and it will be post free since you have that covered on the chemicals. 
, I've just edited that post because it sounded completely different from how I meant it. I do really appreciate everyones advice and the one thing that makes it different on APUG is that there is a lot of experience as opposed to theory amongst the members.
