I purchased two vouchers through Tippr. I contacted customer support to see what they would do in terms of a refund. I received this notice this morning:
We sincerely apologize for how the Weekly Cinema deal turned out, we strive to work only with reputable businesses. In this case it was a surprise to Tippr (and the many other deal sites that ran promotions with them) when they announced they were ceasing business operations. We are not able to offer cash refunds to your credit card as it has been more then 30 days since your purchase. However, I have added $20 worth of Tippr credit to your account for each voucher you purchased, which may be applied to future offers.
Thank you for your ongoing patience and understanding. We truly appreciate it. Have a great day and week.
I sent them a notice back saying that this is not ok

and I expect a full refund. I also pointed out that their "solution" does not make me want to work with them anymore.
