Discount Drug Mart no longer allows these to be purchased with anything other than cash. Hence, no purpose for me to shop there for other things. Any drug store that allows VGCs to be purchased with cc or debit also gets my regular business including pharmacy needs. Any store that goes cash only loses all my business and I transfer any rx needs to another store. I like to bless the store chain that is a blessing to me. Besides that, it's simply more convenient.
