Buying a wheel and a kiln together is the complete setup, and it is a substantial purchase. Bundles exist, and the question worth asking is whether the two items in one are the two you would have chosen separately, because a compromise on either is a compromise you live with for years.
What a bundle usually contains
A small or mid-range wheel, a plug-in kiln, some furniture and a tool set. The value is in the convenience and sometimes in the price, and the risk is that the kiln is sized to make the bundle affordable rather than to fire the work the wheel can throw. Check the kiln's internal dimensions against the largest thing the wheel will let you make.
The mismatch to look for
A wheel that centres four kilograms can throw a bowl too wide for a small test kiln. If the bundle pairs a capable wheel with a very small chamber, you will be firing your best work at somebody else's studio. That is the specific failure to check for, and it is easy to check: largest realistic pot against internal height and diameter.
Buying separately instead
Choosing each on its own merits usually gives a better setup for the same money, particularly if you buy the wheel used and the kiln new. The wheel market has a healthy second-hand supply and the kiln benefits from a warranty and support, which is exactly the split most experienced potters recommend.
What is still missing after a bundle
Clay, glaze, shelves and props if not included, kiln wash, cones, and a bucket. None is expensive and together they are a real addition. Budget for a bag of clay, a bucket of glaze and a set of furniture on top of any bundle price.

Should I buy them separately?
Usually it gives a better setup for the same money, especially buying the wheel used and the kiln new.

Clay, glaze, kiln furniture, wash, cones and a bucket. Not expensive individually and a real cost together.
