Walgreens is now more reliable
Walgreens bot now checks each specific item page before posting about it. Sometimes, an item will have the "Add to cart" option on the search page, but the individual page will say sold out. This extra step accounts for the individual pages and reduces false positives.
Fixed Walgreens URL formatting
Walgreens URLs are case sensitive. Made a small fix to ensure that the parts that need to be capitalized stay capitalized.
