Nice brief list — good options for birthdays, anniversaries, or milestone gifts that stay under $100 (U.S.). I prioritized sets that feel special (attractive packaging or multiple pieces), cover different scent tastes, and are widely available.

1. Phlur Fragrance Discovery Set — ~ $39

• Why: Eight curated fragrances (mini sprays) that let the recipient explore different profiles or layer scents; great value and giftable presentation. Ideal when you’re unsure of a single signature scent. (vogue.com)

2. Sephora Favorites / Cologne Sampler Sets — ~$98 (seasonal variations exist)

• Why: Sephora’s curated sampler/“Favorites” sets include multiple designer minis and often a redeemable voucher for a full bottle — upscale feel without the cost of a full bottle. Good for both men and women depending on the set. Check Sephora’s fragrance gift sets page for current samplers. (Sephora.com)

3. Maison Louis Marie No.04 (or small-format) — ~$98 (full bottles sometimes at this price)

• Why: Popular, elegant unisex fragrance (woodsy/clean). If you can find a travel or 1.7 oz bottle around $90–$100 it makes a refined, grown-up gift that reads thoughtful and luxe. (Prices fluctuate by retailer and format.) (instyle.com)

4. Fulton & Roark Discovery / Complete Collection Set — often discounted under $100

• Why: Includes many of the brand’s solid and spray fragrances—great for someone who travels or prefers sample-to-full-size exploration. Frequently appears on sale at or below $75. Stylish and distinct alternative to mainstream designer gift sets. (esquire.com)

5. Cartier Men’s Icons (small set) — ~$78

• Why: A tasteful men’s discovery/mini set from a classic house — three different Cartier colognes, nicely presented; ideal for a partner, father, or friend who appreciates refined, timeless scents. (vogue.com)

Quick tips when choosing:

• Pick discovery/mini sets if you’re unsure of taste — they’re lower-risk and fun to open. (vogue.com)
• For a romantic occasion, choose a floral/vanilla-led set; for a milestone/“big” occasion, pick a designer house or niche sampler for perceived luxury. (vogue.com)
• Check retailer promos (Sephora, Nordstrom, Macy’s, brand sites) — many holiday and seasonal sales bring full-size sets below $100. (cosmopolitan.com)

If you want, I can:

• tailor recommendations by recipient (male/female/unisex, scent families they like), or
• look up current in-stock gift sets under $100 at specific retailers (Sephora, Nordstrom, Macy’s) and send direct purchase links. Which would you prefer?
