What to ask when you call J J Sullivan Inc.
You can contact J J Sullivan Inc. directly, the phone link above goes straight to them, not us. Prefer to compare? Our optional quote request sends your job details (never your contact information) to up to three validated local dealers, and their prices come back to you through us. Either way, get all six of these in writing before signing anything:
Ask for the standard rolling rate, not the online-discount headline. Confirm whether the quoted price is a first-fill promo or the ongoing rate.
Some dealers bundle delivery into the per-gallon price; others charge a separate per-stop fee. Get it itemised in writing.
If you don't own your tank, ask the annual tank-rental fee and whether it changes after year one. Skip if you own your tank.
Many dealers add a surcharge when the order falls below a minimum gallon count. Ask the threshold and the surcharge amount.
Month-to-month, annual lock, or pre-buy contract? Get the renewal terms and any early-termination conditions in writing.
Auto-delivery and will-call are often priced differently. Ask which the quoted rate assumes and what the other option would cost.
