Red Line SI-1 Complete Fuel System Cleaner 15oz (4 Pack) $49.99 @ Amazon

I’ve had this in my cart for a couple years- it used to be $42 for a 4-pack before Bidenomix; bought it 4-5 times, had it on auto delivery til I realized I had 10 bottles piled up. Seller is good; uses a heavy duty plastic bag sealed with tape in case any of the bottles leak.

Yep, last I bought it a couple years ago it was $12.4x a bottle.
 
$15.99ea at local O'Reilly
I purchased one at O’Rileys for $15.99 today. However out of curiosity found this 4 pack for a cost of $12.49 per
bottle. That’s about $3.50 savings per bottle compared to local shops.
 
Am I the only one who uses Advance Auto Parts?

Been buying it there for years for $10 a bottle.

Currently $17.29 - 15% off and throw in a - $5 speed perk rewards coupon = $10 after tax

I can $10 rewards I can stack and walk away with a free bottle. 🤷🏻‍♂️

The plastic bags are done by Amazon employees. They unbox items and bag them individually (or in multi-packs). It's a safety thing for storage while the product is in the warehouse. All hazardous products go into a special sub-warehouse that seals off in case of spillage. Worked at a fulfillment center for a year. I imagine it nets a discount on insurance for them, maybe.
 
How is this comparing to a gallon jug of Lucas fuel injector cleaner for around $32 T Wally?
