## Description

You know the feeling of being just a few dollars short of a free shipping discount. It's annoying to pay for shipping on a large order, but it's also frustrating to spend extra money on things you don't need just to hit a specific price point. This Connector takes that mental math off your plate. Instead of you opening extra tabs and doing calculations, you just tell your agent what's in your cart and what items you're considering buying. It figures out the smartest move for you. It looks for the best single item or the best pair of items to bridge that gap. The goal is to get you that discount while keeping your total spend as low as possible. You can find this in the Vinkius catalog to get your agent ready to handle these calculations. It makes the checkout process faster and ensures you're never overpaying for shipping or wasting money on unnecessary filler items.

## Prompt Examples

**Prompt:** 
```
I'm at $92 and need $100 for free shipping. I have a $10 book, a $15 candle, and $8 socks. What should I get?
```

**Response:** 
```
To hit your $100 goal with the least amount of extra spend, you should add the **$15 candle**. 

**Breakdown:**
* **Current Total:** $92
* **Goal:** $100
* **Option 1 (Book):** $102 total ($2 overage)
* **Option 2 (Candle):** $107 total ($7 overage)
* **Option 3 (Socks):** $100 total ($0 overage)

Wait, correction: The **$8 socks** actually hit the goal perfectly with **$0 overage**. You should add those!
```

**Prompt:** 
```
Calculate the gap for a $40 cart with a $75 free shipping limit.
```

**Response:** 
```
The shipping deficit for your current cart is **$35**. You need to add at least $35 worth of items to reach the free shipping threshold.
```

**Prompt:** 
```
I need to hit $150. I have a $130 item. From a list of $25, $30, and $40 items, which one gets me there with the least waste?
```

**Response:** 
```
The **$25 item** is your best choice.

**Comparison:**
* **$25 item:** $155 total ($5 overage)
* **$30 item:** $160 total ($10 overage)
