Barbeque packs etc. (Southport PR9)

We have three unopened instant charcoal barbeque packs. We also have a small portable barbeque with 4 small packs of instant charcoal which have been in the shed for ages so may or may not still be usable. The grill top is rusty but could possibly find another one to fit in a hardware shop? Will be going to the tip if no takers.
