All our rentals on this front (including tables and chairs) were just over $500 +tax based on 90 people attending. I’m starting to think this stuff is way more expensive out east because someone else in another thread posted the same thing and they were in Montreal.
However, look around at regular party rental places, not wedding rental places or the more fancy/upscale rental places – this will make a price difference. I shopped around and found one that has free delivery and pickup (woohoo!).
That said, I’m going to buy tablecloths because it’s cheaper than renting (and, it’s also cheaper in that you can sell them afterwards and recoup even more money). A good and affordable places to do this is http://canada.linentablecloth.com/. To give you an example, they are $17 to rent (each) floor-length rectangular tablecloth, but they are as cheap as $11 to buy, plus I can resell them.
I would encourage you to rent dishes and glassware because it’s so much easier to just put them back in the containers they arrived in dirty (you don’t have to clean the rentals!). Trust me, you don’t want to be doing dishes for 100. It sucks. The dishes I’m renting are nice square plates for 55 cents each. If you end up having to buy dishes, it’s not the end of the world, just make sure you have big rubbermaid bins to carry them to and from the venue in (not cardboard boxes!), then you can run them in a dishwasher the next day. I’ve also heard of people going to the salvation army and getting all mismatched dishes and I thought it looked pretty cool in the pics!
We also decided to save a bit of money by having cheaper chairs (black plastic ones – not totally crummy looking but not fancy at all). I waffled on this one for a while but I looked back at pics of my sis’ wedding last summer and she had those, and I didn’t even notice AT ALL until now, it didn’t even register during her wedding. Even in the pics now, looking back, it looks fine (and they weren’t uncomfortable or anything either). These were $1.20 each for me to rent versus about $4 for the nice white wooden chairs which makes a big difference when you multiply it by 90.
Tables were $8.75 for an 8’x30″ table. I just rented the cheapest wooden tables – no one will see them underneath the linens anyway.
We got free shipping because we hit the $300 mininum spend for free shipping within greater vancouver, so call around and see what places can do for you. I found a good rental place in a nearby municipality (20 mins away) and they were cheaper and had the free delivery, and I liked their stuff better, so look around on google, yelp, and other sites.
Hope this info helps! Also, I just re-read that you already have tables and chairs included in your rental, so apologies for that info – I’ll leave it in in case it’s useful to someone else.
