Best Cheap Bulk Essential Oils for Diffusers and DIY Projects
For a large quantity of one scent, the LAB BULKS lavender two-pack offers the clearest bulk option, with two 16-ounce bottles. For variety, consider the 80-bottle set; the 128-piece set lists the most bottles, while the 15- and 20-scent kits suit smaller-scale use. “Cheap” depends on current pricing, so compare the cost per ounce and check whether a set’s small bottles fit your needs before buying.

LAB BULKS Lavender Essential Oil, Two 16-Ounce Bottles

Best for: Buyers who use lavender frequently and want one scent in a large quantity. This listing specifies two 16-ounce bottles, totaling 32 ounces, which is substantially more product than the small-bottle variety sets.
The listed uses include diffusers, room sprays, handmade soap, bath bombs, shampoos, candles, cleaning products, and hair-care recipes. It also suggests blending with coconut oil for lotion. Choose this if your projects repeatedly call for lavender and you can use a large supply.
Limitation: It provides lavender rather than a selection of scents. The listing does not state a detailed ingredient or extraction profile in the supplied product information, so check the full label for your intended use.
80-Piece Essential Oils Set, 5 mL Bottles

Best for: Buyers who value scent variety over a large quantity of any single oil. The listing includes 80 bottles of 5 mL each, with examples such as peppermint, lavender, eucalyptus, tea tree, rose, rosemary, clove, and orange.
The seller describes the oils for diffusers and DIY soaps, candles, massage, and aromatherapy. With many scents available in small bottles, this set is better for sampling different aromas or making projects that use several varieties. Compare the per-ounce cost with larger bottles if you expect to use one particular oil often.
Limitation: Each bottle is only 5 mL, so frequently used scents may run out sooner than a bulk single-oil purchase. The supplied details do not give a complete scent list.
128-Piece Essential Oil Set for Variety

Best for: Shoppers seeking the largest listed bottle count among these options. The product title describes 128 pieces at 5 mL each and names scents including tea tree, sandalwood, lavender, vanilla, and eucalyptus.
That stated variety may suit people who want many fragrance options for home use or creative projects. Choose it when breadth is more important than stocking up on one specific aroma.
Limitation: The supplied product information contains no feature description beyond the title. Confirm the full scent list, intended uses, and bottle details on the listing before purchasing; the number of pieces alone does not show how much of each scent you will use.
MAYJAM 20-Scent Essential Oils Set

Best for: DIY makers or buyers who want more scent choices than a small starter set without choosing dozens of bottles. The listed 20 scents include lavender, jasmine, eucalyptus, vanilla, frankincense, peppermint, sandalwood, citrus oils, and chamomile.
The product information describes use in diffusers, massage, aromatherapy, and DIY candles, soaps, and bath bombs. Choose this if you want a mixed collection for experimenting with different fragrance combinations.
Limitation: The bottles are 5 mL each, so this is a variety set rather than a bulk supply of any single scent. The listing describes the oils as concentrated; follow product directions and avoid applying undiluted oils to skin.
Wtrcsv 15-Scents Essential Oils Set

Best for: Buyers who want a compact starter selection for fragrance and DIY use. The 15 listed oils include cinnamon, lemon, eucalyptus, bergamot, lavender, jasmine, peppermint, tea tree, and chamomile, in 5 mL bottles.
The feature list names diffusers, humidifiers, massage oils, candles, soap, perfume, bath bombs, room sprays, and linen mists as possible uses. It also describes protective bottles intended to limit exposure to heat and light. This set suits someone who wants several familiar scent options in small quantities.
Limitation: The small bottles are not equivalent to buying a large refill of a frequently used oil. The listing’s organic and sourcing statements are seller claims; review the product label if those details are important to your purchase.
Buying Guide: How to Choose Bulk Essential Oils
Do you need one scent or many?
For repeated use of one aroma, compare large single-oil containers such as the lavender two-pack. For testing blends, gifting, or rotating fragrances, multi-scent kits offer more options but less of each oil. Bottle count is not the same as volume: check the size of every bottle before comparing sets.
How can you compare value?
Compare the current total cost with the total listed volume, then calculate cost per ounce or milliliter. For a set, also consider whether all included scents are useful to you. A low unit cost may not be good value if many small bottles will go unused.
What should you verify before ordering?
Read the full listing for the exact scent lineup, bottle size, ingredient information, and usage directions. Do not assume that a product labeled “essential oil” is suitable for every application. Use oils according to the product label, especially for skin or homemade personal-care products, and store them as directed.
