What's your favourite and least favourite part of Christmas dinner?

Whether you go silly for sprouts, potty for potatoes, or think turkey trumps all, there's usually something you love the most on your festive meal. On the flip side, whether you cringe at carrots, gag at the gravy, or want to bin the bread sauce, we also want to know what you don't enjoy. So looking back to Saturday's meal, tell us your Christmas dinner likes and loathes in this week's poll.

What have you switched in 2021?

Sadly, the best deals rarely come to loyal customers. Moving to a new, hot promotional deal is often (not always) the way to slash costs or boost earnings. So tell us, what have you switched in 2021?

How much is a £100 voucher at Amazon, M&S, Halfords and more really worth to you?

These days, many short-lived promotional deals are discounted via store-specific vouchers, not cash. So we wanted to test which you found the most valuable in general, which are most appealing. To do that, we want to value how much cash you'd buy the voucher for if you could.

How do you rate your mobile network's service and coverage?

We want to find out how each provider rates for service (how it treats you) and coverage (how strong the signal is when you need it). In truth, there are only four main networks providing signals – the rest use these, but under their own brands (see our Mobile networks guide for who piggybacks on who). Please rate the firm that provides your mobile phone bill (if you've switched networks recently, please rate the provider you were with the longest over the last year).

When will you be putting up your Christmas tree?

Now that December is upon us, many will be getting into the Christmas spirit by decorating festive fir trees. Depending on whether you prefer a real or artificial tree, this either means a dusty trip to the loft or a journey out to the local shops. Yet, when the right time to do this is can vary wildly depending on who you ask. So tell us, when will you be putting up your Christmas tree? Is it already up? Fake or real tree?

Have you haggled with Sky, BT, the AA or any other companies this year? Did you succeed?

Haggling can result in big savings – on anything from digital TV and broadband to credit cards, breakdown cover and insurance. Each year we try to gauge the success rates of those who have done it. So whether you've gained cheaper prices, extra goods, better deals or reduced interest, please let us know how successful you've been in this week's poll.

Which supermarket is your favourite?

When it comes to grocery shopping you've a lot of choice – from the aisles of Aldi to the wonders of Waitrose. Yet your choice could be costing (or saving) you hundreds. So tell us, which supermarket is your favourite?

How much do you typically spend in total on Christmas?

The festive period is the highest spending period of the year for most people. So this week we want to know, including food, drink, decorations, presents, travel etc, how much do you typically spend in total on Christmas?

Would you pay more to go green?

Going green is top of the news agenda this week, with world leaders meeting at COP26. Yet it's not always easy – or cheap – to make environmentally-friendly choices in what we buy or use. This week we want to know whether you'd be prepared to pay more to go green with these common products or services?

The MoneySavingExpert.com Annual Census

So who are MoneySavers? For the eighth year running, rather than data mining, we reckon the politest way to find out is just to ask. Plus we think you may like to find out a little bit more about who else uses this site (or more accurately, who uses this site and answers the polls).
