Shop where? Surely not in your nearest retail, you'll have hard time to get consistent quality (flicker free, CRI, consistent color temperature, and perhaps most important, longevity)
That's why I use CREE. Fantastic bulbs at a reasonable price - a truly good value!

Or Alibaba if you want even cheaper prices at the expense of some research time.
If you want to skip the middle man, order it directly from the manufacturer.
And there are tons of webshops selling a very wide selection of led lights. No need to send people to the big monopolists.
Most of them won't even accept direct orders.
