Freshwater Quiver Killer

Not sure what the day will bring or what species to fish for? The Scientific Anglers Amplitude Smooth Infinity Fly Line is the perfect line to get your day started. Excelling in flat, calm conditions, the Amplitude Smooth Infinity lets you land flies with delicate precision, attracting otherwise easily spooked fish. A general-purpose taper works well for trout, grayling, bass, carp, steelhead, salmon, and more, and the half-size heavy design lets you carry line if the wind picks up. When the fishing is up close and personal, the long belly gives you the control you need for a precise placement while the dry tip stops your fly from sinking, ruining a perfect cast.

  • Smooth fly line that excels in slow-moving and calm water
  • AST Plus slickness additive keeps your line slicker than ever before

“You offered a first purchase discount and then told me it didn't apply to the bike helmet I ordered? That seemed like a bait and switch. I still ordered the helmet but felt deceived by your offer. Not a good first impression!”
Response from campman.com:

Thank you for your feedback. Our system is set up to default to the lowest available price, and the helmet you ordered was already on sale for over 50% off. This means the sale price was lower than the coupon price and you received the best available deal.

Additionally, the coupon signup clearly states that it only applies to full priced items and cannot be combined with other offers. Here's a screenshot: https://app.screencast.com/fvJS1t5PEPi1a

We love giving hookups on quality gear, but we still need to keep the lights on around here. Your coupon will remain active in our system and attached to your email for whenever you choose to use it.

Cheers,

Campman Support
