Years of research, consultations with some of the worlds best industry professionals, zoos & reptile veterinarians, along with years of trusted & proven testing have went into Intro+. You now have a SOLUTION that is easy to use, safe to use & the most important of all… is EFFECTIVE. We have developed Intro+ to be the best it can possibly can get. We designed the formula carefully to be a dual-purpose product that serves as a treatment when outbreaks occur & as a preventative to use with all new acquisitions. Large, bulky & heavy items may require a little extra shipping. We will contact you if your order requires a shipping adjustment. You may also reach out before hand for a custom shipping quote. LARGE , HEAVY & OR BULKY ITEMS MAY REQUIRE EXTRA POSTAGE Due to Esty’s platform being relatively basic & primitive on the shipping options, Etsy is not advanced enough to allow the option of assigning a different shipment rate for each item variation. We deal with mostly natural items & they all vary DRASTICALLY from unit to unit in size & weight. For example, the cost to ship a small piece of wood may only be $16 dollars but the XL may cost $60+ to ship. We will over up to an additional 10% of the shipping fee, & contact the buyer with any difference needed to ship the item(s). The buyer will always have the right to cancel for full refund if the shipping difference is more than they are willing to pay.
