I once didn't pay the bill for months because my credit card had been stolen and they never did anything about it so unless they changed the way it works, you're good to go.
Small side story: I once had a non-payer when I was selling something expensive who kept delaying to pay. He claimed he had a car accident, etc. etc. but back then, you only had 4 weeks, I believe, to file a complaint. I had to choose between filing the complaint in time and possibly pestering a guy who had just been hit by a car, or I could trust him and risk him trying to screw me over and giving me a bullshit story. Despite believing it was the latter, I didn't want to run the risk of it being the former, so I gave him another week which means I could no longer file a complaint. When eBay then got on my case to pay the bill, I tried telling them I had never received payment for it. Yes, these days, you pay first but back then, it was a custom for sellers under 50 rep to mail out the item if the buyer had over 100 rep. eBay weren't too happy but in the end, they dropped the bill and closed the other guy's account when it became obvious from a a string of complaints that he was making excuses.
