IKEA sells high quality canvas prints (PREMIAR series) for $130. These prints are 78" * 55". Where can I get similar sized canvas prints for my custom photo for the same price? I don't think anyone prints such huge size canvas just for 130 bucks?
IKEA is a multinational retailer that also happens to be the world's largest furniture seller. Considering that it sells upwards of 28BB/yr, they have considerable buying power and marketplace presence. It is not reasonable to believe that a consumer or even a small business could obtain similar pricing to such a large corporation.
For comparison, a popular consumer canvas lab CanvasOnDemand does make 78"x55" gallery wraps that run between $585-664(without a coupon right now). Most popular professional labs do not offer canvas wraps that are larger then about 30"-40" per side. You will have a hard time even finding many options for such a large canvas print.
To give you an idea of the absolute lowest priced canvas wraps I've seen as of recently, the lab I have in mind offers 32"x48" wraps for $99.99 which I consider to be an absolute steal of a price. I consider it to be so low, that I won't even share the "secret lab" :)
Finally, I would ask yourself if you even have images that can stand up to being printed that large. Maybe you do, but do keep in mind that a print from even a midrange DSLR might be challenged if the printer is a quality one.
Overall, if you represent a big enough corporation that can demand these types of prices similar to IKEA - you aren't going to be looking for posted price sheets, you will be working on contracts and negociated deals. If you are a small business owner or consumer, I believe that you simply won't find that price for a canvas(and probably not even for a decent print).
