Reusable mugs can be found for great prices at places such as Ross, Marshalls, and TJ Maxx. Like with reusable water bottles, avoid cups with BPA. See my blog "Three Ways to go Green" for more about that. Many coffee shops sell cups with their logo but do not feel like you have to use theirs.
Award for best discount goes to...
Paradise Bakery: $0.80 + tax for unlimited refills of your chosen beverage (coffee, tea, or soda). You save about $2.00. Did I mention the unlimited refills?
Award for most eco-friendly goes to...
Starbucks has been working hard at becoming more environmentally friendly. When using your own cup, you will save $0.10 on any drink. In fact, their goal is to serve 25% of their drinks in reusable cups by 2015! Don't have your own? You can request your drink to be served in a ceramic cup if you intend to drink it in the store and still get the discount!
I hope to branch out and try some new places. I will let ya'll know if I find a great deal. I encourage you to go explore the coffee shops in your area. Don't be afraid to ask about discounts for using your own cup and about their recycling practices.
What are your experiences with bringing your own cup to coffee shops? Any great places we should go check out?
