Pool store bleach, purchased this year, should be fine -- heat cooks of bleach, but it hasn't gotten hot, yet. Still, Walmart bleach is likely to be fresher.

Pool store tablets (trichlor) may or may not be OK -- read the label. Borates are a way to dilute the tablets so the store can make more $$, but they won't cause any pool problems at all. Copper is altogether different -- do not buy any chlorine with copper listed.

Pool store dichlor should be avoided -- almost all of it is now badly diluted, and some of the chemicals used WILL cause problems.
