FREE Mass Cards

There is a limit of 12 cards per visit. It does mention that donations are welcome when you receive your cards and that there is a donation envelope enclosed with your order.

If you wish to give us a donation after you have received and shared your Mass Cards, we would be grateful. An envelope will be enclosed with the cards you have requested. Or, if you wish, you may make an offering online today.
