Esmeralda runs a local bike shop.She knows a lot of her customers use smartphones with GPS,so she invested in a mobile app that can utilise this technology.She has a couple of idea show to use the app to engage her customers.Can you remove the ideas that do not need GPS?

Notify people of promotional events like a free tune-up" does not require GPS because event notifications can be sent to all app users regardless of their current location, or based on their registered address. "Send personalised coupons to repeat customers" also does not need GPS; customer loyalty and purchase history, not location, are used to identify repeat customers for coupon distribution. In contrast, "Send sales alerts when customers are near the shop" and "Direct customers to Esmeralda’s shop" both explicitly rely on GPS technology to determine a user's proximity to the shop or to provide navigation.
