Learning/Activity books (approx 3-6yrs) (Panshanger AL7)

Hi, if anyone in the WGC area is anyone planning to get rid of any learning/activity based magazines or workbooks for age range 3-6yrs (eg Cbeebies, numberblocks, basic words/phonics/math, pattern recognition, outdoor learning etc) I'd be interested in collecting. Mine is currently very into these, especially those that have sticker or writing activities in. Doesn't matter if already partially completed as long as there's still a reasonable amount left to do. I can collect from Welwyn Garden City. Thank you
