With TurboTax Online, you pay per return, based on what is on the return, and you can see the prices on our website here: https://turbotax.intuit.ca/tax/pricing
Retailers like Walmart, Costco, Staples, etc... sell multi-return packages, which might come out cheaper than paying per return.
If you are going to send the returns electronically, then no signature is needed. If you print and mail the returns, then the person who the return is for must sign the return.
