[i sometimes bring home with me some do-dads such as notebooks, pens, pencils, calculators, post its, clips, screen sweepers, etc. my question is: would any of you like/mind such items included in your packages? ]
yes!
K~ and others JoAnn's must have different policies or stores in other areas must not train the same. At the JoAnn's here in Columbus I check out everything together full price and sale items; and the clerk does does all the coupons at one time. The register here takes the 40% off the top item (or items when more than one coupon) and the week that we had a 10% off total it did take the 10% off everything. I can double check that but I'm sure it was. I haven't asked if they honor other store's coupons though. JA, M &HL are all about 20-25 min. away so don't get there all the time. LQS is only 1 mile though. 
Well lunchtime is just about over will have to finish catching up tonight.
